So i have a proxy server that im using and in my proxy settings (windows) i configured it to use a PAC file so that it will only use the proxy for certain internal sites.

Now the issue im having is that apparently the ELK stack does not like being accessed using a proxy, so i keep getting this error:

Is there anyway around this?

Any help or tips is greatly appreciated!

Thanks

Hello @ghaith

Were you able to fix this issue? Did you try to use proxy-based authentication?
