So this error came out of nowhere… But my searches on the error were less than helpful, so I thought I’d document it here:
After a few days of FileCloud being used successfully, some of my users started getting this error:
Invalid License HostCLFC-00035-00155
This included users who were just fine the day before. However, I was able to access the server fine! And while researching the error, all I could find were links to purchase more licenses…
Turns out the problem was user stupidity! We have an Internal Domain that is similar to our external domain and users were specifically typing in the wrong domain. i.e. https://files.INT.domain/ rather then https://files.domain/.
Even though I have a rewrite rule in the Apache Config, it only rewrites the URL in HTTP not HTTPS. So if the users types in the URL with HTTPS:// it never takes effect.
Anyway, my testing found that you will get the license error if you use an incorrect URL. I’m not sure if it is a HTTPS Certificate mismatch on the different name or the license itself is hard coded to a specific DNS, but I did find that it works if you use an IP Address…
Hope this helps someone else.
