404

This error occurs during an integrated transaction and during pairing and can mean that the Merchant ID (MID) and Terminal ID (TID) is not connected to Tyro.
It can also mean the Tyro EFTPOS machine has lost its internet connection and cannot be contacted by our Integration Server.

Troubleshooting steps:

1. Check your internet connection
   1. In an internet browser open www.tyro.com/selftest and make sure six green ticks are displayed on that page
   2. Check the EFTPOS machine is signing on when connected to Ethernet/WiFi
2. Check the details in the TTA
   1. Make sure there is a MID and TID entered, and it has just numbers, no spaces or letters
   2. Confirm the MID and TID entered matches what shows on the EFTPOS machine

 

403

This error indicates that the integration key shared between a POS and Tyro EFTPOS machine are not matching.

 

Troubleshooting steps:

1. Please reattempt the pairing process ensuring the MID and TID are correct (having administrator permissions may be necessary) as the error may not necessarily mean the MID and TID are incorrectly input, it may only mean that the key the POS sends does not match the Tyro EFTPOS machine's current key
2. If multiple windows logins are being used, the pairing process should be completed individually for each login credential used

 

Name Resolution Failure

Name resolution is the process of converting a hostname to an IP address, so a Name Resolution Failure occurs when the Domain Name System (DNS) used by your computer can’t convert "integration.tyro.com" into the relevant IP address.
A very common cause of this Name Resolution Failure is that there is no internet connection to the POS computer.

Troubleshooting steps:

1. Reboot your modem or router followed by a reboot of your POS device
2. Visit https://tyro.com/selftest/ to test your internet and network connection to our Tyro server (six green ticks should be displayed)
3. If your page loads but does not display six green ticks, please contact your IT or ISP to allow a connection to Tyro's domain
