I'm using the Epos JS SDK (https://www.epson-biz.com/modules/ref_epos_sdk_js_en/index.php?content_id=1). The SDK is used inside a Vue App, the app is then built for an ios device. Now, if I run the app local on my browser, i can print and everything works fine. If the app runs on the ios simulator or on real device im getting an ERROR_TIMEOUT from the connect callback of the epson SDK.

Here is a code snippet for printing: https://www.toptal.com/developers/hastebin/aneqidehos.js

Bonjour is also enabled on my printer.

Thank you for help.
