Hi, We've just updated our pFsense from 21.05 to 22.05 which included an update of HAProxy from 0.61_5 to 0.61_7. We have 4 Apache web servers behind it running http.
We've got a rule in advanced passthrough, that adds a Content-Security-Policy header of 1120 characters, which if we remove this line, we don't get errors.
The 500 errors all contain a PH-- error like: (some details obfiscated)
