You have trouble connecting the mobile device to MobiControl or ERP.

Solution

...

Business Central (NAV)

• The port number used by SOAP Web Service of the NAV server tier, should be open for the network used by the scanner.

This is the only requirement 

For troubleshooting go to I can't log in from mobile device

MobiControl - For Remote control

1. WiFi Internet connection

   1. Test: Are you able to open a website using the browser on the scanner?

      1. Not a 100% guarantee as port 80/Internet may be blocked

2. Firewall 

   1. Customer MobiControl: Port TCP 5494 must be open for outbound connection (IP address:   Firewall port 5494 must be opened for outbound connections for MobiControl to work. The Mobicontrol Server has the IP address 40.68.196.181 ) + and hostname ds1.mobi.taskletfactory.com and ds1.mob2.taskletfactory.com and ds2.mob2.taskletfactory.com + 40.114.220.164 and 13.95.171.202 port 5494.

   2. Partner MobiControl: Port TCP 5494 must be open for outbound connection (IP address: 13.81.28.131 + ds1.partnermobi.taskletfactory.com 

   3. the MTU size needs to be set to 1,500 bytes

3. As the connection is HTTPS, a certificate is in play. The date on mobile device must not be to far off the current date - or else the HTTPS connection will not be allowed.
