That is normal https port, some websites may reference it directly while others skip it, it is fine. You can edit permissions on a per site basis to always ask, block, or allow location access by clicking on the lock icon > Connection (secure/unsecured) > More Information, then change to Permissions tab and set it how you want.
If tired of being prompted about location on all sites you can go into Settings > Privacy & Security, scroll to Permissions, click Settings next to Location, click ‘Block new requests’ and save changes. Per site allow/block/ask can still be configured.
You can try seeing if you can set the speed/duplex of NIC/ports manually if auto-detection keeps getting it wrong.
Unifi I like the APs for mesh & multiple SSID+vlans but I keep them on dedicated vlan with zero internet access because I don’t trust that I properly followed instructions to disable opted in analytics/telemetry. The mgmt software is alright but new UI wastes a lot of space. The PoE switch was alright until it stopped being able to keep a config last year. USG router I kept less than a year because it was too slow with any useful features enabled. I’ve glanced around at replacement APs here & there but pretty much waiting until I have more wifi 7 compatible devices and that’ll be another couple years.
