Don't bother asking for help without including the EXACT command you ran and the EXACT error you received.

[–] JustAnotherKay@lemmy.world 5 points 23 hours ago (1 children)

What port do you have SSH set to? What ports did you change the services to? Is the SSH port open?

[–] ComradeMiao@lemmy.ml 1 points 9 hours ago (1 children)

SSH is standard port 22. The services were 3000, 5000, 8888, and something abnormal I think 5675. 3000 and 8888 were taken. First time it said 8888 was taken so I edited to 8188. Second time it said 3000 was taken so I edited to 3001. Then I lost SSH.

[–] JustAnotherKay@lemmy.world 2 points 9 hours ago

Have you hit it with anything to check if your ports are still open? There are a handful of tools for the task

[–] HybridSarcasm@lemmy.world 9 points 1 day ago

We don’t have any rules about low quality posts. So, I dont’t have cause to remove this. Though, I also won’t lock it because I want everyone to downvote it into oblivion.

OP: you can save this post by actually adding details in an edit.

[–] fuguOne@lemmy.ml 13 points 1 day ago

Based on the data that you provided, I think you need to check the flux capacitor.

[–] JustEnoughDucks@feddit.nl 3 points 1 day ago (1 children)

Hey, I had a similar thing happen to me. It turns out the faulty container brought down my entire LAN network. The reason you can't ssh in is likely because your router is stuck at 100% usage trying to figure it out.

At least that is what happened with my old Archer A7 and damn nextcloud.

[–] ComradeMiao@lemmy.ml 1 points 9 hours ago (1 children)

Did you try removing the container? What did you do to fix it? I think you’re probably right. I ended up just moving my data, sense I could use the terminal and send files out, and reinstall fedora server.

Thanks for sharing! :)

[–] JustEnoughDucks@feddit.nl 1 points 9 minutes ago

I had to physically log into the server (I am not using a VPS) and docker compose -f ... down the container in order for it to be solved. After a downgrade of nextcloud it was solved and the next upgrade I did, didn't experience the same issue. I ended up ditching nextcloud anyway because after an update ~8-12 months ago, the login page has never loaded since, so it can't be used. I found out I rarely used it anyway.

[–] Coldmoon@sh.itjust.works 14 points 1 day ago (1 children)

Could you give us even the slightest bit of detail? What containers? Did you try pinging the device?

[+] ComradeMiao@lemmy.ml -10 points 1 day ago (2 children)

That’s really all I did. There were port conflicts, I changed in the yml then lost contact.

On the server ssh is fine. I can ssh into another server but not into it. Can ping 1.1.1.1.

Can’t access containers or ssh

[–] Coldmoon@sh.itjust.works 7 points 1 day ago

There is too much to decipher here

[–] Evkob@lemmy.ca 5 points 1 day ago (1 children)

They meant pinging your server from another device, I assume.

What error(s) do you get when you try to SSH into your server?

By "can't access containers", I assume you mean via devices you're trying to connect to the server with? Can you still access the stuff you're running in the containers directly on the server via localhost?

I'll echo what the other commenter's have said and you need to give us more info. "I added two containers" is pretty much useless if that's all we have to go off of to start troubleshooting. More details on what exactly you did, any troubleshooting steps you've already tried, what specific errors you get, etc.

[–] ComradeMiao@lemmy.ml -2 points 1 day ago* (last edited 1 day ago)

Ssh just runs forever until I stop it. Sometimes it says timed out.

Weirdly I can access my public sites but not my local services via my desktop to that server.

I explained it that simply because that’s all I changed. Ran two docker compose up via cli. Once the issue arose I turned them both off and removed them.

That guy is attacking me about configs but the configs are gone as are those two containers.

I can ping from the server. I can ssh from the server. I cannot ping or ssh to the server.

[–] crusa187@lemmy.ml 9 points 1 day ago

You say you changed port configs in the yml, but then refuse to share said yml when people ask to see configs.

If this is some sort of trolling attempt, going to have to rate it 0/8.

Let this be a lesson to you - don’t modify port settings unless you’ve triple checked the documentation. It’s easy to mix them up with docker. And don’t ever use a known port value for a service like ssh, that’s just asking for trouble. Docker provides other ways to access the virtualized cli.

[–] JASN_DE@feddit.org 12 points 1 day ago (2 children)

Well? What did you do?

[–] just_another_person@lemmy.world 8 points 1 day ago

[–] just_another_person@lemmy.world 10 points 1 day ago* (last edited 1 day ago) (1 children)

Details please.

I'm assuming you forced a port conflict somehow.

[–] ComradeMiao@lemmy.ml -5 points 1 day ago (1 children)

I tried to run hanabira via cli. There were port conflicts but I changed them in the yml.

[–] just_another_person@lemmy.world 5 points 1 day ago (1 children)

I don't think you changed them in the right way, or didn't restart. Post configs.

[–] ComradeMiao@lemmy.ml -5 points 1 day ago (1 children)

So I already removed those two containers. What can I share with you?

[–] just_another_person@lemmy.world 4 points 1 day ago (1 children)

Like everyone else is saying. POST CONFIGS.

[+] ComradeMiao@lemmy.ml -6 points 1 day ago (1 children)

For what? The config for the containers I installed are removed as are the containers.

[–] just_another_person@lemmy.world 3 points 1 day ago (1 children)

Just GTFO if you don't want help. Later.

[+] ComradeMiao@lemmy.ml -14 points 1 day ago* (last edited 1 day ago) (2 children)

You asked for configs. I asked you which configs. You get upset?

You asked me twice, I answered and asked for clarification twice. What is your problem?

Blocked.

[–] BCsven@lemmy.ca 4 points 19 hours ago

People are replying like they are because you have asked for help but aren't able to provide details on the steps, the yml files, or other commands you executed. Essential it is like when my wife calls me on my phone and says "I'm lost, where am I?" And I have no clue where she is because she can't provide me street names or what direction she is travelling. Basically nobody here knows where you are.

[–] onlinepersona@programming.dev 15 points 1 day ago* (last edited 1 day ago) (1 children)

Are you trolling or is this the first time asking for help?

Imagine if someone told you their car didn't work, you asked what they did, and they said "turned the key in the ignition twice and it doesn't start". ? No make, no model, no description of sound or recording of the action, no idea when they got the car checked, no photo of the warning lights, nothing. Would that be enough information for you to help?

As @just_another_person@lemmy.world said: post configs! What is your OS, what commands did you enter, what are the contents of your yml files, which containers are running, which images are you using, etc. Nobody can help you otherwise.

Add the information to the original post.

[+] ComradeMiao@lemmy.ml -12 points 1 day ago* (last edited 1 day ago) (2 children)

How can I know which configs they mean without them clarifying? I’m on the server via terminal. I cannot copy when it can’t ssh.

Thanks for continuing to be rude when I clearly asked for clarification twice. You two belong on reddit.

Blocked.

[–] BCsven@lemmy.ca 2 points 19 hours ago

You could scp them from server out, you can setup simple http and grab via web, you can use a phone and take a picture, you can read them on the server and type them here. Lots of ways besides ssh into the machine from a client

[–] Saik0Shinigami@lemmy.saik0.com 12 points 1 day ago

Why bother asking for help if you're not going to do the bare minimum of bringing us up to speed on what you're running and how it's configured. Just to be a complete jackass and "block" everyone the moment they ask for any of that information in order TO HELP YOU.

To this point the only facts we know...

Your running docker. You added two containers. One of which might be Hanabira. That were run via docker compose. SSH is working, but not... because you didn't actually explain that well at all.

That's it. That's all you've provided and I had to literally read EVERY thread to find that. That's all we got. Nobody can help you. And with people outright asking you for more, and your hostility in return to those trying to help you. Nobody else will want to help you. Including me.

Good luck. But I wanted you to know that you're the jackass here.

It's mildly funny though that you live up to your .ml instance preconceptions.

[–] miss_demeanour@lemmy.dbzer0.com 9 points 1 day ago (1 children)

Did you unplug it and plug it back in?

[–] ComradeMiao@lemmy.ml -3 points 1 day ago

Yes :,(
