Safari26 randomly not loading pages with websockets?

Im using Figma and home assistant frequently and both websites are after updating several devices to iOS26 and MacOS26 not loading Figma and Home Assistant Website consistently.

It seems to work for a moment if you clear cache and website data, afterwards its failing again.

I got Problems in Safari on those devices (all latest OS, before update never had any issues, nothing else changed):

M1 iMac

M4 Mac Mini

M2 MacBook Air

iPhone 15 Pro

My M4 MacBook Air is working fine - I don't know why, same Apple Account - makes no sense :(

I´ve read that there have been problems while Beta - looks like there is still something wrong.

Mac mini, macOS 26.0

Tahoe is in its point 0 release. There are bound to be issues that will take another year to resolve in point updates. Also, at this early date, third-parties may have not adapted their websites, or applications to be completely compatible with Tahoe. Contact the third-party vendors about any updates or procedural workarounds they may offer.

Same happens here. M4 Max. The thing is, everything was working with Sequoia 15.7 and Safari 26.0.1.

While when upgrading to Tahoa 26.0 with Safari 26.0 (26.0.1 is not available for Tahoa?) the websockets stop working.
