We have a CSV located in the following directory on our FME Server. We receive the following warning whenever we run a job that utilizes the CSV:

 

USERNAME FME Server: SSL certificate verification failed for host 'MACHINENAME.DOMAINNAME.com:443'. HTTPS connections

 may not be secure. Disabling verification of SSL certificates. Message: HTTPSConnectionPool(host='MACHINENAME.DOMAINNAME.com', port=443): Max retries exceeded with url: /fmerest/v3/resources/connections/FME_SHAREDRESOURCE_DATA/filesys/FOLDERNAME/CSVNAME.csv?disposition=attachment&accept=contents

 (Caused by SSLError(SSLCertVerificationError(1, '3SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1051)')))

 

We see a slightly different warning in Workbench:

 

USERNAME FME Server: SSL certificate verification failed for host 'MACHINENAME.DOMAINNAME.com:443'. HTTPS connections may not be secure. Disabling verification of SSL certificates. Message: HTTPSConnectionPool(host='MACHINENAME.DOMAINNAME.com', port=443): Max retries exceeded with url: /fmerest/v3/resources/connections/FME_SHAREDRESOURCE_DATA/filesys/FOLDERNAME/CSVNAME.csv?disposition=attachment&accept=contents (Caused by SSLError(SSLCertVerificationError(1, '&SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1051)')))

 

The FME Server is configured for SSL and is running as a domain account that has the R/W privileges to the folder where the CSV is stored.

 

Does anyone know what could be causing this warning and how to resolve it?

I have a similar situation since a recent FMEServer update... API calls from Python failing to FMEServer with SSLError.

I suspect that there is an issue accessing FME Server over the web. But you may check permissions by adding a CSV Reader to the canvas and reading directly from the local FME Server file share. e.g. C:\\ProgramData\\Safe Software\\FME Server\\resources\\data\\FOLDERNAME\\CSVNAME.csv

 

I have some further questions in order to continue troubleshooting.

 

How long has this error occurred for? If it only started recently, have there been any changes to your network?

 

What version(s) and build(s) of FME Server/Workbench are you using?

 

Is this occurring with the FMEServerResourceConnector, or CSV Reader/ HTTPCaller?

 

Do you have multiple proxies in this environment and are they managed by a PAC file?

 

Thank you.
