If yes; which version of Safari are you running?
Did you change or notice anything else, like alerts in the bottom right, change internet providers, laptop, plugins, etc?
Still having issue yes.
I’m running on Safari 16.6.1 BigSur 11.7.10 intel core i7
As I keep logged in, something may have changed during one of those long periods. But nothing I can think of.
Same happens in a private window (which usually discards some run time issues )
