Hi Anne,
did you test QGIS 3.0 also?
Could you create an issue in issue.qgis.org tracker?

I found that one, that seemed related https://issues.qgis.org/issues/18634

> The problem: if QGIS uses an HTTPS (SSL) WMS service, the WMS works nicely
> in QGIS desktop. However, if you use the same .qgs project file on QGIS
> Server, all requests to the HTTPS (SSL) WMS server result in an  SSL
> handshake error.
> This (still) happens on:
> Ubuntu 16.04
> QGIS server 2.18
> An example WMS https server showing the problem is:

> A workaround could be to use the HTTP version of the WMS instead of the
> HTTPS version. However, the capabilities of many HTTP services advertise
> endpoints.
> The SSL problem also arises when trying to use WFS services over HTTPS
> from QGIS Server.
> Is this a known problem? Is there a workaround? Should I file a bug report?
> Thanks,
