I am trying to get a php script to work on an internal IIS server. I have php working on this server with several scripts without any problems. These scripts are making calls to other internal servers in the enterprise but a new script I am working on makes an API call out to an external website for ServiceNow. I am very limited in php skills, and I did try to search as best I could to come across a post that was similar to my problem but just couldn’t find one. I am running php on windows with v7.3.11.
The php script is not completing and a wireshark capture shows syn, client hello, ack, and then fatal with Unknown CA. This is a public website that has a 3rd party well known issuer. From this windows server I can browse to the url with no cert issue.
If I understand correctly php may use the default windows certificate store. I did try to import the cert into windows store but that didn’t seem to help. I also tried to update the php.ini to point to specific curl.cainfo but that did not seem to help either. Maybe I am missing something in either of those attempts?
I have reached my limit on where to go next for php help. If I can browse to this url without cert issue from a web browser on this server but the php api call gets unknown CA what else could be the issue?
Many thanks in advance!
