Gitlab runner blocked by IP

I use gitlab.com and gitlab-runner on my own server. Today I see that my job is pending. The reason - gitlab block my runner by IP!

Now, i cannot deploy my application for bug fix. Pipeline quota: 0% used;

curl response:

curl https://gitlab.com
Forbidden

runner logs:

ERROR: Checking for jobs... forbidden               runner=9f09eda9
ERROR: Checking for jobs... forbidden               runner=9f09eda9
ERROR: Checking for jobs... forbidden               runner=9f09eda9
ERROR: Runner https://gitlab.com/... is not healthy and will be disabled!

How to add my ip to white list?
