I encountered a strange issue with KNIME Server 4.16.2 installed on Azure via marketplace image.
When attempting to login on the Webportal, the first attempt always fails without an error message. Then a second attempt succeeds and open Webportal, but with a ‘Sorry this page does not exist’ message. After clicking ‘back to home page’ everything works normally.
After some digging I found out this is likely a browser issue:
- opening a second tab and navigating to webportal opens it, suggesting the initial login attempt was already succesful
- the issue exists on Chrome and Edge, but NOT on Firefox
- the server access logs reveal different entries for Chrome/Firefox:
Firefox log entries
[30/Mar/2023:13:54:01 +0000] “POST /knime/webportal/j_security_check HTTP/1.1” 303 -
[30/Mar/2023:13:54:01 +0000] “GET /knime/webportal/ HTTP/1.1” 200 982
Chrome log entries

[30/Mar/2023:13:43:18 +0000] “GET /knime/webportal/ HTTP/1.1” 304 -
Using incognito mode does not fix the issue, nor does allowing cookies for the KNIME page.
Any suggestions on why this happens, and how to handle it?
