Sorry to reach out, I searched for an answer but I didn't see anything relating to my specific issue, sorry if I missed it. I used to connect fine to Snowflake using Datagrip with JDBC driver 3.13.5. Yesterday, in order to be able to use Snowflake with Tableau, I installed the ODBC driver, as well as ODBC Manager. Since, then, impossible for me to connect using Datagrip, I get the following error message :

JDBC driver encountered communication error. Message: Exception encountered for HTTP request: <URL>: nodename nor servname provided, or not known.

The connection string is: jdbc:snowflake://:443 and used to work fine until yesterday. I tried updating to 3.13.7 (last version), but same issue. Does anybody have an idea of what I did wrong and what to do? Thanks a lot in advance for your help and support, have a great day! Nicolas

  • Hi - that’s obviously not a valid connection string, there’s no url in it for a start. Please update your question with the actual connection string (masking any information that would identify your account/user/password/etc) – NickW Oct 05 '21 at 11:32

    Thanks for your feedback @NickW. I thought I had written it properly but the obfuscated part disappeared. Here it is: jdbc:snowflake://https://XXX.snowflakecomputing.com:443 – NicolasK Oct 06 '21 at 14:38
