Yesterday, I tried to open the SharePoint portal but unfortunately, the page can not be displayed! Thence,
- I checked the proxy settings in the browser.
- I made sure that all servers within farm running.
- I checked SQL server status that running.
Finally, I found out a strange user symbol beside database name with (Single User) !!
I tried to expand the “WSS_Contene” database, but I got the below error
The SharePoint Content database is not accessible.
