How to fix this issue with Discord bot?

Question

css

I am writing a bot for the Discord messenger using the Discord4J Java library. There was a problem establishing a connection to the Discord API. The StackTrace shows that the socket error. I read the Discord documentation and there was a suspicion that the API has request limits and it has its own for each request. If so, then I thought that after some time a new limit would be provided, but this did not happen in the next week. Has anyone come across this problem and know how to fix it. Below is the most ill-fated StackTrace.
