For me, I have to do ‘url: “http://pictrs:8080/” ‘ instead of 127.0.0.1 in the config.hjson file

I checked this, and my lemmy.hconf file already has the host for pictrs set to http://pictrs:8080.

The only thing that has worked so far is manually unsetting my site’s image icon by unsetting it directly int he Database.

And yes… I see sync issues as well. I’ve responded to some comments multiple times because I didn’t see my original response at a later time.

I also added the proxy network to both lemmy-ui and pictrs, but that did not resolve the issue.

I had to manually remove the sites icon from the database for the site to start working again.

I’m going to try removing the proxy network and instead use pictrs:8080 on the internal network as that feels more secure.

Note: this seems like it has something to do with the database, and something getting royally messed up post upgrade.

After trying all sorts of network hacks and updates, I eventually just decided to backup my Postgres container, and nuke it.

With a fresh Postgres DB running along with 0.18.0, my self hosted site is back online. Of course, my local post history and all my subs are gone… but at least my site is operational again.

I’d advise anyone self-hosting to not upgrade to 0.18.0 yet.

Yes. Absolutely does happen on other instances that have thousands of users.

Oh, Big-O notation? I never thought I’d see someone else mention big O notation out in the wild!

:high-five:
