I have found some similar questions to kubernetes API server not starting but the error message I am getting is different. I have had a working cluster for several months, went to login yesterday and it was offline. Looked around in some log files and this is what I get below, looks like its trying to make a DNS query to my local DNS Server which has been working fine for the last few years and still works fine. The Log is below and I'm pretty frustrated because I don't know how to fix this, have made no config changes and hoping the community can help.
