Hello,
When trying to access dashboards or the DataMiner home page (http://dataminerlab02.xxxxx.yyyyy), we have the following error displayed on the webpage:
Following points was checked :
- WAS and W3SVC services are running.
- HTTPS tag is correctly configured. The name attribute is configured with “dataminerlab02.xxxxx.yyyyy” which is one of the subject alternative names on the certificate. This name also gets resolved to the IP address of the DMA.
- The user configured a URL rewriting inbound rule for HTTPS: Configuring HTTP to HTTPS redirection. I verified that they set the redirect type incorrectly (was not set to “Found (302)”) but after changing this, the issue persisted.
- The user issued new certificates a couple of weeks ago for these DMAs because they had already expired at the end of 2024.
- As a workaround, we tried disabling the URL rewriting rule but the issue of not able to access dashboards still occurs (webpage with Service Endpoint not found).
Are there other points we could check ?

Has this server been used to host another application in the past? It seems to still look for a WCF service, so there might still be some old configuration that hasn't been cleaned up entirely.
Verify all the application pools that are listing on this host+port. Removing IIS and installing it again could also help. If you still have issues, I can take a deeper look if I can get access to this system.

After investigating directly on this system, it turned out that an element in DataMiner registered a web service on port 443 directly on HTTP.sys. Stopping the element fixed this issue. (Connector "Generic Webhook Alarm Table")
