@Bigwaff I like your suggestion and
@basslik should give it a try, but he reported that he doesn't experience the problem with OCLP 2.0.0 (only started with OCLP 2.0.2). Why would the combination of Private IP and OCLP 2.0.0 work, but not the combination of Private IP and OCLP 2.0.2?
EDIT:
@basslik If experimenting with Wi-Fi Private IP (I think that
@Bigwaff means setting the Private Wi-Fi address to "fixed"? Not sure) doesn't fix your issue, I did notice Network connectivity issues that were partially resolved (and sometimes re-broken) by subsequent Sequoia Betas. Others are experiencing Sequoia network issues as you may have seen in other forums. You may find help
here.
EDIT2: One more thought - I have found in Sequoia that setting Ethernet to Inactive and then Active again (System Settings > Network > Ethernet > "Make Inactive" and then "Make Active") fixes connectivity issues that I have with Remote Desktop in Sequoia 15.1 Beta (24B5055e).
