I have no idea what web browser you use, but yes, I had a few glitches before/since installing Windows 10 version 1803 using Internet Explorer 11 (slow phase out), but works fine for Microsoft Edge.
I mainly use Internet Explorer 11. For Internet Explorer 11 Reset in Tools/internet options/Advance did not fix the problem, but Internet Explorer 11 Restore advance settings in Tools/internet options/Advance fixed it though.
It might be a corrupted web browser/virtual private network error or server error on your end.
