When we upgraded our proxy from 6.7.3.14 to 6.7.5.6 we saw that users were facing issues connecting to websites.
Users are getting tcp_error message when trying to access websites and also some websites are loading very slow.
When we bypass the user IP everything is working fine.
We upgraded from 6.7.3.14-->6.7.4.9-->6.7.5.6
Now we have rolled back to 6.7.3.14 and everything is working fine. Anyone faced similar issue before?
