I can log in to the site on my phone and using chrome but since the server migration I can not log in using Edge, my usual browser. I cleared the history but no go. The user name and password are entered but it claims an issue with my 'browser not sending the csrf cookie or it was invalid'.
In Edge I had to go to settings > cookies and site permissions > manage and delete cookies and site data > see all cookies and site data > search for DPrevived and then delete everything. It still took a couple of attempts and a refresh before I got logged back on.
