Hello alimardanov,

file sending timeouts on railway with telegram bots are usually caused by a connectivity issue between railway containers and api.telegram.org. the quickest fix that railway staff themselves confirmed is to try switching your service to a different region in your service settings and redeploy, can you also share your exact error logs and what region you're currently on? that will help narrow it down faster

Timeout errors when sending files via the Telegram Bot API are usually caused by file size, network latency, or default timeout limits in your bot library. Kindly check and confirm back.
