Yep, I tried that. The only way around this was to disable nostr:npub1mea2vwcu06qf7e4x00wd902vj54qnn2jacq76ldntrgfhtvhlpqqrvqane VPN and turn off the kill switch, a suboptimal workaround... Help

If split tunneling is enabled and block connections without VPN is disabled you shouldn't need disable the whole VPN.
Make sure in Proton the split tunneling mode is set to standard and nextcloud and Firefox beta are added to the excluded apps.
