When a request in HTTPS is sent to execute a page of a site, call a REST API, consume a SOAP webservice, authenticate with AuthIdentifie, the request may fail with the following error:
A system error was detected while sending the HTTP request. Error Code: 100138
This appears if the connection cannot be properly encrypted. The encryption failure may be related to :
- the request,
- the configuration of the workstation,
- the certificate or the configuration of the server being contacted.
The following points have to be checked:
-the given URL does not contain spaces or characters that do not conform to URLs.
-if the request is sent with an httpRequest/restRequest variable, check that the headers do not contain ["accept-encoding"].
-the station is up to date with Windows Update, and its security settings, supports TLS 1.2 and SSL 2.0 minimum and that the certificates databases are up-to-date.
-the server is using HTTP 2.0
