SharePoint Site Error on MsTeams

[yohannes_adeba]

To make it simple for our organization's channel members to view the site, I embedded a SharePoint site into the MsTeams channel.(because employees use MsTeams everyday). Users can simply open all work tools in one location thanks to the SharePoint Site's combined PowerAPPs, Power-BI, List, Forms, Yammer, and document library elements.

Problem
For the previous few months, everything has been operating flawlessly, but now, whenever I access it, I frequently encounter this error. Although I believe this to be a network issue, I wonder whether my settings may possibly be a contributing cause. So, can somebody assist me in resolving this problem? Here is a screenshot of it.
