@Marketmaker, what dialect are you using?
{ "requestTimeout": 300000 } should work for MySQL and MariaDB, for MicrosoftSQL you need to use{ "options": { "requestTimeout": 300000 } }
btw how can i get extend request limit, beside using IP Authorization? i mean like 200 request per 3 minute, can i just buy 2 different license and using this http://fingerprints.bablosoft.com/#keys to combine??
