All avatars showing up like this: [image] When opened in a new tab `http://forum.example.org/user_avatar/forum.example.org/user/48/681_2.png\` responds with HTTP 500. I’m using an S3 upload for images (blackblaze). Seems that an avatar image is uploaded there. Tried disabling it, still the same issue. Doesn’t seem like a proxy issue. Tried binding port to the server, same issue. Opening `http://localhost:8082/user_avatar/forum.example.org/user/48/681_2.png\` results in: [image] This only happened after new update: 3.6.0.beta2-latest Already ran the two rake avatars:refresh and rake posts:rebake as instructed in similar issues.

Any errors in the browser console or in /logs?

Yes, console og: 681_2.png:1 GET https://forum.example.org/user_avatar/forum.example.org/othman/24/681_2.png 500 (Internal Server Error) Image (anonymous) @ ajax.js:133 XMLHttpRequest.send o @ ajax.js:188 A @ ajax.js:201 #Qa @ chat-api.js:583 listCurrentUserChannels @ chat-api.js:299 (anonymous) @ chat.js:210 loadChannels @ chat.js:209 (anonymous) @ chat-setup.js:140 eZ @ plugin-api.gjs:3522 g @ chat-setup.js:44 initialize @ chat-setup.js:199 (anonymous) @ app.js:239 Promise.then (anonymous) @ start-app.js:8 await in (anonymous) (anonymous) @ discourse-boot.js:13 (anonymous) @ discourse-boot.js:1

Is there a firewall or some network limitation here?

No. What’s confusing is that this same backend works for images in regular posts but not avatars.
