CSLU Log Message: HTTP Server Error 502: Bad Gateway

[Joris Deprouw]

Hi Guys,

I have a customer who had a working CSLU configuration.

When I check the logs today. All devices are showing the following message in the log.

045492: Mar 15 2022 13:38:01.338 CET: %SMART_LIC-3-COMM_FAILED: Communications failure with the Cisco Smart License Utility (CSLU) : HTTP Server Error 502: Bad Gateway

From the device I can ping the Smart Satellite. So connectivity is ok.

Any ideas to what might cause this error?

Thanks,

Joris

Any details on the Bug? Is not public available. Maybe facing same error, at least from logs I have.

I think it was once public. In any case, it's still listed in the release notes Version 8 Release 202112 as resolved:
