This annoying bug seems persistent as it already exists in the 3.105.
You can read about it and the solution in this previous post from wellnw
TL;DR:
- kill
gl_health
process & delete thegl_health
package - install travelmate (readme) and luci-app-travelmate
- enter the luci page Services/Travelmate
- configure
If I remember correctly, I tough the team added a fix? @Johnex
