Why can't I connect to Apex servers?

I'm encountering an issue where I'm unable to connect to Apex servers. Could you please explain what could be causing this problem? Is it a server-side issue or could it be something on my end? Are there any steps I can take to troubleshoot and resolve the issue? Additionally, are there any known outages or maintenance periods that could be affecting my connection? I'd appreciate any insight you can provide to help me get back online and access Apex services.
