If your bot is requesting a lot you will easily get into this error. It can be solved by increasing the rate limit:

https://matrix-org.github.io/synapse/latest/admin_api/user_admin_api.html#override-ratelimiting-for-users

Alternatively this is also possible via SQL:

matrix-org/synapse#6286 (comment)

EDIT 1

I still have the issue. The changes did not work. I asked in the synapse chat and they adviced me to search in the reverse proxies. I will keep this post up to date when I find new ideas to solve the issue.

It should be noted that the Ruby SDK chooses not to try to intelligently handle any low-level communication issues, it will only handle expected application-level errors that can occur - things like the Matrix server responding with a 429 Too Many Requests.

If you're seeing errors with the socket not opening within the timeout, you can either expand said value

api.open_timeout = 120

or use Ruby's exception handling to retry the action that failed.
