Only one thermostat starts flame Weil-McLean

I have a Weil-McLain boiler CGI5PINS2 and 2 zones (upstairs and down) but only the downstairs thermostat is successful in starting the flame while the upstairs causes a repeating clicking noise. Wiring is a mess (way it was installed before I bought the house) and I have checked the thermostat wiring and see no apparent issues...thoughts?

The upstairs thermostat isn't properly connected... to something... or, if you have zone valves, the zone valve to which it is connected is not working properly, or improperly connected.
Messy wiring isn't just a matter of esthetics. It can conceal all manner of errors and bad connections. I'd probably begin by cleaning up the wiring.Br. Jamie, osb

Is the system zoned by zone valves or circulators? You can easily check the second floor at the appropriate control to determine if its a wiring issue or a control issue.
There was an error rendering this rich post.

Thanks for the suggestions, I am double checking all the wiring. Just to clarify, the upstate thermostat is able to open the zone valve when it is demanded but if it requires to start the flame, it just keeps trying. the downstairs thermostat is able to do both without issues. I keep the temperature higher downstairs as a workaround (objective is to have the thermostat downstairs start the flame before the upstairs unit demands heat). https://photos.app.goo.gl/1ruqsCv2MocCtzbE90
