login fails often with username/password

[gruijter]

I do a login 24/7, once an hour, using username/password, at three different schools. For one school the login fails around once every 3 to 4 times. This happens in the test password part:

MagisterJS/src/magister.js

Line 458 in 017f475

throw new AuthError(err)

What happens when you do the login from the command line a couple times after each other? (Without changing any code)

then same behaviour. Might be coincidence during my trial, but first login succeeded. Then 10 seconds later I get a timeout on login: Error: FetchError: network timeout at: https://accounts.magister.net/challenge/password
then third time I get Error: InvalidUsernameOrPassword
then fourth time succeeds again, and the same cycle of failure types repeat themselves.

So it seems to go from success > timeout on challenge password > invalid usernameOrPassword

Weird, when I pass the token from the last valid login (in stead of username/password) I seem to get a valid login, but the profileInfo = null.

Trying to login after that with username/password results in invalid usernameOrPassword everytime. And after some minutes waiting, I can login again with username/password.

The issue for that token problem is #90

But can you retrieve any other data such as grades and appointments if you login with a token?

I can't cause it gives an error while retrieving the privileges from the login, cause they're null

Could you re-open this issue pls @lieuwex?

Oh woops this shouldn't have been closed indeed.

So I installed alpha4, and retested the logging in behaviour.

I now made a scheme where I still login every hour to the three different schools/students, and retrieve some information (grades and lessons mostly). I seperated the time between the three schools/students 10 minutes apart. If I have a token, I will first try to login with the token. If that fails I will try to login with username/password as fallback.

I notice from my logging that when using the token, it also often fails to login (once every 3 to 4 times). This happens for multiple schools.
The behaviour of logging in with username/password seems to be the same: it fails every 3 to 4 times.

In short: the login problem still persists. It seems to fail randomly in about 25-35 % of the attempts. This goes for both the username/password method, as for the token method.

@gruijter that the token fails could be because it expires after some time. Don’t know why the username / password login fails tho. When testing I logged in with and without a token like 2 times a minute and didn’t experience any issues. When I’m home I’ll try to replicate the issue but I can’t really promise anything.
