Connection to a new server sometimes interrupted

I recently started working at a new place where we are using Keycloak to connect to multiple servers. I set up a new server and sometimes (I know this is vague, I cannot really tell when, but it occurs a few times in an hour) the connection to the server via Keycloak is not working for a few minutes (the Keycloak admin interface however is working smoothly, therefore I am assuming that the problem is not related to Keycloak). Are there any logs from Keycloak that might point me to the problem of the connectivity?
I understand that this is a vague question, I am new to Keycloak. If there is any more information I can provide to make it better understandable, please let me know.
Thank you very much for your help.
