My Win 11 (25H2) desktop occasionally sends me to renew access on my gmail account (via IEEE organization, services10.ieee.org) where I enter my walter.dinkins@ieee.org email and then it sends acknowledgement to Google or YouTube on my iPhone. Now I keep getting error message "Unable to connect". I am able to connect on my iPhone via the Firefox app but not on my PC. I added https://mail.google.com and hppts://accounts.google.com but still not luck. Any other suggestions? Regards, Walter
