Hi, just wondering:

• What's your stack?
• Are you using a reverse proxy?
• What exactly is returning a 502 or 503 error, and when?
• What specifically appears in the logs? the 502 or 503.
• I see that the 503 only appears once, and the 502 appears every other time, so I would assume the errors aren't related.
• Also, the only 503 that appeared was before performing an action that returned a 200, 1:02 seconds after. Was it the same action or a different one?
• Regarding the 502 errors, they specifically occur at 1:00 or 1:01 minutes before the 200 error, which is also strange, but could be directly related to a process or task that runs one minute after the error. Except in the last case, where the 502 appears at 4:14:54 and the 200 at 12:46:12, but that would be the only instance. And considering that there is at least one case where it was different, I tend to think that: A) They are two different processes that use the same code that causes the error.

B) It is the same process, but the user can "create" it (for example, create a chat, a friend request, etc.), and then there is another process where something related to the previously created element is terminated, modified, or deleted and the error appears
