Hotspot Server Showing Invalid on RB750GR3

Please be advised that I recently purchased a MikroTik HEX RB750GR3 router in India (Serial No: removed by mod).

I purchased this router to set up a hotspot with a voucher system for my small homestay business. However, I am currently facing an issue with the hotspot configuration.

I created a bridge including Ethernet ports 2 to 5. Although internet connectivity is available on all four ports, the Hotspot Server status shows as “Invalid” and appears in red. As a result, hotspot control is not functioning.

I am currently using RouterOS version 7.21.3 (stable). As part of troubleshooting, I also downgraded the OS to version 6.49.18, but the issue persists with no improvement.

I have reviewed multiple configuration and troubleshooting videos on YouTube. I came across a video mentioning that, since 2025, there may be a known issue with the Hotspot feature requiring an additional configuration code or adjustment. However, I have not been able to resolve the problem.

I have attached a screenshot of the hotspot server status for your reference.

Kindly assist me in resolving this issue at your earliest convenience.

You should post your configuration, as an export, instructions here:

A screenshot showing only a small part of the configuration Is not enough to (hopefully) spot where the issue Is and suggest remedies/corrections.

In newer versions of RouterOS a hotspot will show up as invalid if not permitted by device mode, see https://help.mikrotik.com/docs/spaces/ROS/pages/93749258/Device-mode
