  • 1.  error OC

    Dear community.

    I just upgraded from 20.1 to 20.3 and I get the following error in the OC

    Is this causing any error in the OC itself, or just seen in the logs?

    In some cases this error can be the result of a firewall between the OC and CABI servers, so make sure the communication is fully allowed between OC and CABI.

    But sometimes an error like this can also be a benign message as long as it is not associated with any unwanted behaviors.

    It is also possible that this error would be resolved by applying the later updates to 20.3, eg. the October 2021 patch. 

    However,  I would instead recommend continuning the upgrade through to 20.4x since 20.3 is no longer supported and then troubleshoot the issue only if it persists on the supported release.

    Additionally, this error also appears

    As I wrote in the other thread, check if the fix in the Broadcom article (that is now only available in Google cache) is right for you. Also, some problems are solved with upgrade to a newer version.
