We had a web hook on push going to an internal jenkins that suddenly stopped last week. We had made no internal network or firewall changes. But the webhook suddenly stopped working Wednesday last week around 10am.
We are getting this squid error from a 10-18-21-51 which i'm assuming is an ip? Even though it is formatted with dashes. According to the documentation we have all the outgoing ranges listed here in our firewall. Again this was all working for months before last wednesday.
We verified we have these ports in our firewall. https://support.atlassian.com/organization-administration/docs/ip-addresses-and-domains-for-atlassian-cloud-products/#Outgoing-Connections
Anyone have any idea how to track down what changed?
