SAML Metadata URL did not connect and pull data successfully

mattermost 9.8
keycloak 22.0.5
Still reporting the same anomaly

I also tried to integrate keycloak with OpenId.
The exception is -> tls: failed to verify certificate: x509: certificate signed by unknown authority
I confirm that all my certificates are tls certificates issued by ca

I also tried to integrate openId with gitlab
The exception is -> tls: failed to verify certificate: x509: certificate signed by unknown authority

integrate openId with keycloak4.5
The exception is -> invalid character '<' looking for beginning of value

Can you tell me what I did wrong？

Hi
mattermost 8.1.9
keycloak 22.0.5

Thanks

Thank you, given that v8.1 has gone out of support on May 15th, would you be open to upgrading to v9.5 or a newer version to see if the issue still reproduces?
