Shipstation (webservice) with TB 1.1 and PHP 7.3 not working

[x97wehner]

With PHP 7.3 and TB 1.1, Shipstation is not able to work correctly when transmitting tracking numbers. Seems to work fine with PHP 7.2. Shipstation is a webservice connection. Seems to be the only issue I've had with 7.3. Any how to resolve?

Do you have any error log for the problem?

I don't. The error only shows on the shipstation side.
