I’m currently testing the KNIME Server with the latest AWS Marketplace template (KNIME Server Small for AWS). On my desktop I work with the latest Analytics Platform (v3.7.1.v201901281154). There seems to be a version conflict similar as discussed here:
Is there a fix or workaround for this problem or do I have to downgrade my Analytics Platform
The version of KNIME Server on AWS right now is 4.7.3 (we still need to update the images). To ensure compatibility, you should use Analytics Platform 3.6.2.
is there a possibility to manually update the server via SSH?
Yes, that is another possible option. Please find the update information here: https://docs.knime.com/2018-12/server_update_guide/index.html#update
You can ignore the references to knime-tomcat.jar, this is not relevant in your case.
Note that besides updating the application server, you’ll need to update the executor as well.
