TM1 Server Explorer keeps making me enter server name every morning. Why?

[bz_boy]

Hello all. Each morning when I try to connect to Perspectives through our Citrix portal, I get an error saying it cannot connect. This is because it is not saving the connection string for the TM1 server. So every morning I have to open Server Explorer in TM1 perspectives, go to File then "Options"  and enter in the Connection string. I also check the box for "Integrated Login". Once I do that, it connects fine. Its more of an annoyance than anything. Other members of our team have only had to do this one time and it saves the connection string from then on. Does anyone know what could be causing this to make me do this every morning?

Any help would be appreciated! Thank you

BTW we are using excel 2016
