This Syracuse Server release resolves an issue introduced in Syracuse 12.19.x when using a forward Proxy Server (Configured in Administration, Administration, Settings, Proxy configuration) to access external URLs. You will see error "write EPROTO F4120000:error:0A00010B:SSL routines:ssl3_get_record:wrong version number"
The fix is available now via our FTP site at https://ukienterprisedownloads.sage.co.uk/Support/SageX3/X3V12/Syracuse/syracuse-server-12.19.12.2.jar.zip
