Hello, I tried different ways:
https://dva1622:5001/webapi/auth.cgi?api=SYNO.API.Auth&method=Login&version=1&account=****&passwd=****
https://dva1622:5001/webapi/auth.cgi?api=SYNO.API.Auth&method=Login&version=1&account=****&passwd=****&format=cookie
https://dva1622:5001/webapi/auth.cgi?api=SYNO.API.Auth&version=3&method=login&account=****&passwd=****&format=cookie
But the result is always the same.
What am I doing wrong? DSM 7.1.1-42962 Update 2
But as I understood in my case, the port does not need to be specified, then I get error 103
