URI::InvalidURIError in Devices#show

Hello everyone,

Recently we have been testing a TP-Link router and trying to get it to work with our ACS Server.
With recent firmware updates the following problem has emerged with the GenieACS-GUI:

This error has appeared before and was typically fixed by changing the “path value” in the router:

But as of a few days ago we have not been able to “recover” the device with GenieACS-GUI. The base configuration of GenieACS-GUI hasn’t been modified apart from the “config/summary_parameters.yml” file. If we register the device on another GenieACS Server it works just fine.

Does anybody know what the problem could be?

Thank you,
James
