Youtube - an error occured while signing through phone

[rahul khera]

When I am trying to access the youtube app I cant log in and I get an error code. The weird thing is that this happened a couple of hours ago.It worked perfectly before.. What should i do? I tried clearing the cache and installing an old version but it still isnt working. But when I am signing it through a browser it works.Any ideas?? I am using one plus 5T
