Reach out to your network administrator to check VPN configuration, firewall rules, etc.</p><div style="clear:both;"></div>https://community.appian.com/thread/65617?ContentTypeID=1Wed, 03 Apr 2019 18:33:39 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:97dcc642-eeb3-42fb-a197-eef2ad7d8ff2Myles Weber<p>I would suggest using SAML instead. SAML is typically on top of an LDAP or Active Directory deployment anyway.</p> <p><a href="https://docs.appian.com/suite/help/19.1/SAML_for_Single_Sign-On.html">https://docs.appian.com/suite/help/19.1/SAML_for_Single_Sign-On.html</a></p><div style="clear:both;"></div>
