I’m still having problems after applying the “fix”. My belief is that it’s the RDS connector and not the web connector that we are using. I’m on QBPOS v12 and QBDT Pro 2021. I’m getting the certificate revoked issue when I use remote (QBDT on remote computer - RDS) as well as local (QBDT on POS computer). I know I have an old version of QBPOS, as well as a paid (non-subscription) version of QBDT and have no intention of upgrading (POS is end of life anyway) but my expectation is that a certificate revoked issue should still be corrected for as long as I choose to use this software.
