about signing in arcgis portal through arcmap
hi everyone
when i use arcmap to sigin in portal, arcmap popup a window embeding internet explorer. The window sometimes correctly show login screen, but some times popup script error window. it's really weird. The embeded internet explorer webpage url is https://x.x.x.x/portal/sharing/oauth2/authorize?client_id=arcgisdesktop&redirect_uri=urn:ietf:wg:oau.... After many tries,I find if I use Internet Explorder to browse above url, may result web adapter can not connect portal and I conclude that only use windows server's internet explorer may result such problem even turnoff enhanced mode, and other browsers like chrome dosen't have such situation.
Dose anyone encounter such problem?how to solve it?
environment：arcmap 10.8.1 , arcgis server 10.8.1 , windows server 2016
