After updating to version 3.1.0, I have such errors in the log. I am asking for help in solving the problem.

Nextcloud 19.0.6

Hey there,

I have the same problem with the app (Version 3.1.0). As soon as I enable the app, my log file gets spammed with these log messages (16 messages/second).

Nextcloud 19.0.8

Hi, i have the same problem:

I'm facing the same issue. Any update for this?

It seems to fail here:

 56         /**
 57          * @param $ip
 58          * @param $range
 59          * @return bool

 64         private function matchCidr($ip, $range) {
 65                 list($subnet, $bits) = explode('/', $range);

Which is the code from stackoverflow (at least the 1st one above).

How can this be debugged nicely?

Hi, i have the same problem:

PHP Error: Undefined offset: 1 at [nc dir]/apps/limit_login_to_ip/lib/LoginHookListener.php#65

NC: 21.0.2

Solution: I have removed the ip restriction in the security section

[jbits-se]

This error seems to be caused by having an invalid entry under Security -> Restrict login to IP ranges Make sure you have no empty lines or non CIDR entries.

[Irkhar]

I deleted the entry with an empty IP address and it no longer reports an error in the logs. Thank you

This issue should be fixed in new version (v4.0.0-beta1). Feel free to reopen if needed :)
