Not working integration with MS Exchange…
Connection reset by peer - SSL_connect
After some pressing on “connect” button I got another screen:
Your connection not private.
The certificate of the domain belam.lv could not be verified. This may allow hackers to steal your credentials. If you are sure that you are using a self-signed certificate, you can press “Proceed”. Otherwise, please “Cancel”.
After “Proceed” I got next screen, input my Exchange EWS url, got Exchange folder List and following error:
SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate)
Exchnange use valid wildcad cert from trusted public CA, also internal cert from our Enterprise CA.
I did import both CA certs (Sectigo Root CA and Our Enterprise Root CA) into system root ca container.
- openssl s_client -connect exchange:443 -servername exchange
- openssl s_client -connect adfs:443 -servername adfs
returns valid about servers certificates.
Please point me to correct logfiles what i need to check, or some commands, what can help me to troubleshoot my problem.
Exchange has ADFS authentication, i hope this is ok.
