Small update. Make one test run again, before release.
@openoms I reverted back to the old version to clear another bug first. Can you second check:
Could not reproduce this problem. I have synced and modified the latest script uninstalled Tor and reinstalled Tor + BTCPay together and then one-by-one too.
Don't see a reason in the changelog which could cause this.
v1.0.3.164 working fine:

OK it looks like its something with my TOR desktop browser - BTCPAY Server is showing up on my mobile TOR browser. So we are good here.
New major BTCPay release 1.0.4.0 with Payjoin support (requires an other hot wallet, not tested on the blitz yet):

Will test and update here.
Their LND support is still partially broken, unfortunately only works properly with LND 0.8.2 for now.

Installation looking good on 1.5RC1 with:
https://github.com/btcpayserver/btcpayserver/releases/tag/v1.0.4.0
and
https://github.com/dgarage/NBXplorer/releases/tag/v2.1.24
Managed to generate a hot wallet and the payjoin link is available to be paid with another BTCPay wallet as described in: https://docs.btcpayserver.org/features/payjoin
OK is merged - looking for final testing on v1.5 RC2 (coming as soon as lnd 0.10.0 is out).
Test look good .. closing for v1.5 RC2 release.
Merged update. TODO: One final install test.
Updated to v1.0.4.2 as discussed in https://github.com/rootzoll/raspiblitz/pull/1140#issuecomment-620759409
