I've seen similar errors from cp2012, cp2013, and cp2023 when trying to edit/preview/save and view page histories.

In case it helps, another specific error code: 880596179 - cp2013

Hi, we had some connectivity issues earlier. As soon as we were alerted and started checking, the issues recovered. We suspect the root cause to be a network maintenance ongoing at the time, but the problem is now resolved.

Thank you for the quick response.

Thanks
