Who Me Too'd this solution

I got a similar message (RSA_verify failed: 140539036088064:error:04097068:rsa routines:RSA_private_encrypt:bad signature:fips_rsa_sign.c:423:

2022-09-26 12:46:03.112 +0000 [PERR]: Invalid SIG.) after we upgraded from PANOS 9.1.12 to 9.1.13.  We get this error when trying to establish connections between Palo Alto and Cisco devices.  IKEv1 works and using IKEv2 with pre-shared keys works. We even tried updating to PANOS  9.1.14 and 10.1.7.  Using IKEv1 is not a solution due to STIG requirements.  If anyone else has run into this and has a solution I'd like to know.
