There is a known issue for ChatGPT whereas ChatGPT can't be accessible for Asian Users especially if ZIA users are using Hong Kong as Primary data center.
To resolve this Issue. ChatGPT traffic must go through to either Singapore or Taipei Zscaler DC.
sample PAC script as below:
/* for PH and MY users who wants to use ChatGPT then use SG node. As ChatGPT doesn’t work in HK node for Asian users*/
if (((shExpMatch(country,"Philippines")) ||
(shExpMatch(country,"Malaysia"))) &&
(shExpMatch(host,"*.openai.com"))) {
return "PROXY ${sin4.sme.zscalerthree.net}:80; DIRECT";
}
Please do note that proxy sin4.sme.zscalerthree.net may vary which depends on client's Zscaler cloud tenant.
