Hey @GBafnja,
If you have the Performance Display turned on in your settings, that should show a server ID. If you're running into this on a consistent basis, can you pull that info up if possible? That would help us track if there's a certain server having issues or underperforming if we start to see a number of reports about that.
Aside from that while you mentioned not seeing this behavior otherwise, have you tried any particular connection troubleshooting steps so far?
I'd definitely try going through the steps above to clear your DNS and make sure you have the appropriate ports opened for Apex specifically on your router.
