We've added a 3845 router in CSM. When using SSH, we could add the device. When using HTTPS as protocol, we couldn't access the router and we got the following error
Unable to Communicate with Device An error occurred during device communication via HTTPS. Device communication was performed using following URL: https://IP_address/level/1/ios_web_exec/commandset
Http and https have been enabled on the router, we can open https://IP_address from web browser without problem.
When opening directly https://IP_address/level/1/ios_web_exec/commandset from web browser, nothing is shown in the web browser.
with other model of router, we've got no problem.
We need to run device manager from CSM and need to access HTTPS from it.
