Web service - failed certificate verification

[fpaco]

Hello all,

We are facing difficulties to setup a web service in OTRS. OTRS should contact other tools through REST API but trying to do so, we got the following in our logs:
Response content: 'Can't connect to archer-val.steria.fr:443 (certificate verify failed)

Code: Select all

Response content: 'Can't connect to my-fqdn.org:443 (certificate verify failed)

LWP::Protocol::https::Socket: SSL connect attempt failed error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed at /opt/otrs/Kernel/cpan-lib/LWP/Protocol/http.pm line 46.
'

We tried to add the faulty certificate (which is self signed) to the trust store of the server (running CentOS 7). Running a curl command on the server was successful but we still get the above-mentioned error in OTRS.

Would you have a hint to solve this?

Thanks in advance

what name does the the certificate have and is it readable by the otrs and webserver user? Are you using actual versions of LWP::UserAgent and IO::Socket::SSL?
