Looking at your signature, as much as I can tell without your certificate, it appears that a WWDC certificate is included and that the team ID of the certificate used to sign equals the team ID in the pass.json.
I can see a couple of minor discrepancies between the WWDC certificate in a known good pass and yours so I would start by replacing your WWDC certificate with the latest from the Apple Website.
Also check your server time and the signing date and time and also that your Apple Developer subscription is still valid.
If you are using a third party library to sign the pass, check that it has been properly updated to meet both the signing date and WWDC certificate inclusion requirements - a number of public libraries have not been updated since these requirements became mandatory.
