Action is strongly recommended to prevent problems with your Let's Encrypt certificate renewals. A client you have used to access the Let's Encrypt API in the past 60 days has identified itself (its "user agent") as "Go-http-client". This is a generic name for the underlying library that the client uses, which does not give us enough information to track and resolve problems with the client or clients.
This mean, i must set user-agent for http client without set default, but have any rule for user-agent name ?
