Web CLient: "TCP Init" Error

2023-05-24T11:55:08.548000Z

Hmmm.here's the odd things (I have CSYS support so I also submitted to them and they said HTTPS worked ok on example project).

Example project Web Client "out of the box" from CSYS states HTTP or HTTPS URL supported in the comments of the PRG.
This implies (to me) no unique HTTPS Cert generation, etc. required. I type the HTTPS URL ( https://api.weather.gov/gridpoints/TBW/69,116/forecast/hourly ) in browser, displays fine. I run WinPLC project and "TCP Init Error"
No external inputs to CFC Block I can set to fix.
Definitely on my end, but stumped for now.

Feedback really appreciated on this. Any further insights I'll take otherwise, gonna have to "grind it out"....

I was going to revisit WebVisu running over HTTPS (which I think Security Agent generates Certs for) for any clues.

I dont think Security Agent can generate Diffie Hellman parameters, which is what you need for tls connections without client certificates.

I ran "security Agent" which is the latest cert. gen approach. Thanks though.

have you run cert-gendhparams from the Plc shell

*Note: previous posts on this did not resolve my issue.

Using latest IIOT Library download with Web Client and associated example project on WinPLC.

Use the provided HTTP URL: sURL : STRING(1024) := 'http://httpbin.org/get' (works fine)

Use my HTTPS URL: sURL : STRING(1024) := 'https://api.weather.gov/gridpoints/TBW/69,116/forecast/hourly'

gives me "TCP_INIT_ERROR" Unable to initialize the TCP socket.

All Libraries look good as provided with the example project and updated accordingly.

?- something with my Socket and HTTPS credentials. Just not sure were thos knobws are adjusted.

Regards
