Client banned based on IP?

Hi, my erpnext hosted on ubuntu 16 was working fine till this morning. Then suddenly I started to got “Refused to connect” responses. After a while I have realised Im getting this error if I usig my home internet connetction with a fix IP address. As soon as I change to any other network (so other public ip too) all working in order. Is there any IP blocking mechanism in the standard ErpNext system ? Or what can be the issue ? Thank for the ideas in advance
