@aapeliv @nabramow several people have reported this recently:

• This ticket
• Impossible de mettre une photo #5553
• profile picture doesnt up load #5463
• Posting a profile pic #5455
• I can't do m'y photo in profil #5437
• Can't upload profile picture #5407

This seems to be a pretty critical issue since it is coming up a lot and can be preventing users from using the platform (since they can't message or request until they have a profile pic uploaded).

This seems to be an intermittent backend issue. Perhaps it is performance-related since the site has been loading slow at times.

I was able to replicate the issue, but only intermittently:

I can't tell if this is definitively a performance issue or an issue with file size / resolution limits. However, I was able to uplaod a 12000 x 9000 so I don't think it's a resolution issue, and I was able to upload a 20.2MB photo so I don't think it's file size either.

Hopefully closed by #5583. Flask was only listening on IPv4, but nginx was sometimes proxying to the IPv6 address, and that was failing with a failed (111: Connection refused).
