Sideloadly errors 1100 and -29004
If you're experiencing; "Failed: (1100) Your session has expired. Please log in." or "Login failed (-29004): This action could not be completed due to possible environment mismatch." then please attempt the fix below. (This fix is only for Windows)
Close iTunes if it's opened or kill it from Task Manager.
Open Start > Run (Or press Windows Key + R) > type in %ProgramData% and hit enter.
Next, navigate inside Apple Computer > iTunes. The complete path will be: C:\ProgramData\Apple Computer\iTunes
Now you can safely rename the "adi" folder to "adi.bak" or just delete it.
Open Sideloadly and then try sideloading an IPA and you will be asked for your Apple ID password again.
