Im running Buster / ISPConfig3.1.14p2 using Apache 2 as the web server. Ive got an odd issue currently - websites served as SSL have an initial delay of up to 10 seconds before actually loading the first time. Once loaded the client can browse with no further delays. This happens on *all* SSL sites but not the unencrypted. The remote browser just waits on "Establishing Secure Connection". No errors appear in apache logs at all or the sites. CPU load, ram usage etc is minimal. Certs are all LetsEncrypt generated from within ISPConfig and all check out as valid. What i have found is editing the Apache config and disabling OCSP stapling removes this delay completely but obviously this is a bit of a hack. Any idea where my config has gone wrong or whats causing this issue?
