MS TEAMS APP scripts erros in loggin window.

Hallo. I am not sure thai is right place to solve my problem (not enough serious) bot the MS support gave mi link to this community.

I am a student and I have got office 365 account (Office 365 A1 for students). I can log in to office365 web site and use all apps. I have got problem with automatic video meeting by MS Teams. My teaches sent me a link and I have got only manual access ant I have to wait for my teacher approval. Resetst of my class have got automatic acces. Additionaly wheh I want to loggin to MS Teams apps by my stident account I have got ecripts erros (line:20, letter: 20521,code:0, url: https://aadcdn.msauth.net/ests/2.1/content/cdnbundles/ux.old.converged.login.pcore.min_69srsug0xepqypwpw0_7aw2.js  ) Do you want co continue starting scripts on thi page. But when I use my private MS account I can log in to MS TEAMS app with no problem and with out any errors.

Sory for my English:)
