I’ve actually had pretty good success with ChatGPT when I go in expecting it to hallucinate a significant chunk of what it spits back at me. I like to think of it as a way to help process my own ideas. If I ask questions with at least a base understanding of the topic, I can then take whatever garbage it gives me and go off and find real solutions. The key is to not trust it whole cloth to give you the right answer, but to give you some nuggets that set you on the right path.

I think I’ve basically turned ChatGPT into my rubber duck.

So...it's working now? I haven't touched anything yet, but I just checked my instance again and it works perfectly fine on desktop now. It always worked through Voyager, so I was able to let people know there was an issue. If it comes back I'll try some of these suggestions to find a more permanent fix.

 

I don't know when it started, I usually check my instance through the Voyager app and it never showed a problem, but I'm suddenly getting "server error" and 502 bad gateway errors on my instance on desktop. I haven't made any major changes (read, any at all) since I last confirmed it worked on desktop.

Checking the logs I don't see any obvious proxy issues but I am getting weird connection issues in lemmy-ui:

Where on earth can I even begin to address this?

Meaning I just wait a bit and retry later?

Upgraded to 0.18.5, which now gives me this error:

lemmy-lemmy-ui-1  | API error: FetchError: request to http://lemmy:8536/api/v3/site?auth=AUTH_KEY failed, reason: connect ECONNREFUSED IP_ADDRESS:8536

I created a gist with my compose file: https://gist.github.com/osiriswrecks/26a875576d3bbcf11923d7715ac15e6e. It should be stripped of all private info. I tried changing the version from 0.17.3 to 0.18.0 and the server returns a gateway error after restarting.

 

Hi! I'm hoping for some guidance upgrading my instance. I'm still running on v0.17.3 because I ran into some issues upgrading to 0.18 and didn't have time to really figure it out. Now that the current release is v0.19, I have people on my instance asking to upgrade and I don't blame them. Can I simply point Docker compose at the latest release, or do I have to do incremental upgrades? What do I need to look out for with v0.18? Documentation seems to be pretty slim for whatever breaking changes happened during that release cycle and how to deal with them. Any help is appreciated!

EDIT: Thank you for all the help! I also had to update pictrs and fix some small config issues and then everything worked as expected. I'm now on 0.19.1!

About freaking time. I have it as an option but I hate using it. I’ve been looking for alternatives for a while now because I just expect to lose a couple hundred bucks in “processing” for every project I work on.

It's a bold strategy, Cotton. Let's see if it pays off for them.

 

EDIT: I have it working now! I had to set up DKIM and configure my server so Digital Ocean created the proper PTR records. Now email is being sent to spam but at least it's making it through!

Hopefully this is the last time I need to bug you guys here about stuff. :)

I added a postfix relay to my Lemmy instance and configured the email settings in my lemmy.conf file but no matter what I do I keep getting a "no_email_setup" error when I try to test the SMTP server. Is there an obvious step I'm missing?

This is my full docker-compose.yml:

And my lemmy.hjson has this block:

  tls_type: "none"
}
 

I set up my own personal Lemmy instance yesterday and everything seems to be up and running. I installed it on Docker with SSL enabled on a Digital Ocean droplet.

The only thing that doesn't seem to work is federated search. I can search local communities, but no matter what I do I can't get it to recognize other instances. I've tried:

And nothing shows up. I've tried the same search terms multiple times over the past day or so and nothing is changing. My instance has federation and federation debugging enabled (although I can't figure out where the federation debugging outputs yet, because nothing in console log changes), and as far as I can tell there are no errors in the Docker logs that could point me in a specific direction. Where can I start looking to properly debug this?

EDIT: I needed to expose my lemmy backend to the proxy network. This answer here helped me get to the solution. https://lemmy.world/comment/150173

So looking at this again now, am I taking that whole block and adding it to the container's nginx.conf? If so, does that mean I have to change what port it's currently listening to (because there's already a rule in the file for port 80)?

There's a comment in that server rule that says "this is the port inside docker" and a comment immediately after that says "this is facing the public web", which confuses me.

The one meant for the Docker container or the one on the host?

[–] penguin_ex_machina@lemmy.world 1 points 1 year ago (4 children)

I think this is where my lack of experience with Docker is showing.

I spun up a DO droplet and installed nginx, Docker CE, and Docker Compose. Then I went through the instructions on the page you linked to and it set it up just fine but when I went to my droplets IP address it wouldn't connect. I had to add a config file that pointed traffic coming into the droplet on port 80 to redirect to the Docker container instead. Am I overcomplicating it?

I seem to be having a lot of lag at the moment, and my post was created twice so I'm just going to delete the other one and start from here...

So I have this set up per the instructions. My instance is on a Digital Ocean instance, and I'm using nginx on the host to point to localhost:1235, but that's about all that conf file is doing. Is there something else I need to do?

 

I'm playing around with my own instance of Lemmy but I keep getting a "websocket connection failed" error in my console. I'm having a really hard time understanding how to set up nginx for websockets - I'm more used to Apache and not familiar with WS at all. Is there documentation hiding somewhere that will help me set up my proxy forwarding properly?

EDIT: Solved! Check out my solution here: https://lemmy.world/comment/141648. Thanks everyone!
