issue with 1.1.1n

[Ray Crumrine]

Hello,
I have a strange issue with 1.1.1n. I am getting error

SSL SSL_ERROR_SSL (Handshake): Level: 0 err: <336151573> <SSL 
routines-ssl3_read_bytes-sslv3 alert certificate expired>

but not all of the time. Only when I try to access 
us-east-va.sip.flowroute using tlsv1.2.

I have tried two other sites using the same configuration and they work 
fine. Is there a simple configuration change or do I need Openssl v3.0?

Checking with 
https://decoder.link/sslchecker/us-east-va.sip.flowroute.com/5061 
everything checks fine???

Any help appreciated.
