v3.8.5 (Windows): certificate expired message (evrprog@zergpool) about nanominer

[FibreFoX]

@UselessGuru There is nothing wrong, just the certificate is not valid anymore (which already is printed in your logs).

You can check the used TLS certificate via:

openssl s_client -connect evrprogpow.eu.mine.zergpool.com:13002

(you can install OpenSSL on Windows via Chocolatey using choco install openssl)

Results into this for me:

CONNECTED(000001B8)
depth=2 C = US, O = Internet Security Research Group, CN = ISRG Root X1
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=1 C = US, O = Let's Encrypt, CN = R3
verify return:1
depth=0 CN = zergpool.com
verify error:num=10:certificate has expired
notAfter=Oct 14 07:21:01 2023 GMT
verify return:1
depth=0 CN = zergpool.com
notAfter=Oct 14 07:21:01 2023 GMT
verify return:1

Looks like other miners just ignore the validity-time ( notAfter=Oct 14 07:21:01 2023 GMT). Other ports might have a different TLS cert, you should inform the providers.
