No REST Endpoint. Cant connect to server

[ThomasRobsonPG]

Hello,

I recently upgraded from 4.4.4 to 4.7.1

I had no issues prior to this, but now it wont let me connect to our servers.

I have gone in and tried to edit them and include the port, but it wont let me accept that and the “MountID” is greyed out.

Any help would be great

Hello,

Quick workaround: try changing https and port 8443 to http and port 8080, and see if that works. If it does, it could be a proxy in between, or it could be a missing SSL certificate preventing HTTPS communications from being established.

Correct fix: verify if there is any proxy information or SSL certificates that were in your old installation that might not be added to the new installation yet. Correct missing info and retry.

Hello,

thank you for your response.

Is there anyway that i can check the SSL Certificates for the old installation? Or how i could i could correct that missing info?

Hello,

Much depends on how you did your upgrade.
But, to resolve this, you can try any of these:

• Import the required SSL certificate(s), see this video: Resolving Common KNIME Certificates Problems - YouTube
  • The certificate would be provided by your company’s IT or network team.
• Use http instead of https (unencrypted communication).
  • For KNIME update sites, this is found under File > Preferences > Install/Update > Available Software Sites.
• Possibly change the proxy configuration you’re using (File > Preferences > General > Network Connections).
• Should the proxy certificate be preconfigured in Windows by your IT, you can use the Windows trust store. To do so, add these two lines at the end of the knime.ini within the KNIME installation folder (while KNIME isn’t running):

-Djavax.net.ssl.trustStore=NONE
-Djavax.net.ssl.trustStoreType=WINDOWS-ROOT

Please let us know if you have any issues with these approaches.

Best regards
