Right now there is only one connection.
Yes, I was thinking to use the general purpose HTTP integromat module to try to circumvent the issue.
Right now I have a total of 5 connections (in integromat) because, making a new one, is the only "fix" i found to get it back to work. When i do a new one, it last for less than i day, working fine, before giving again the same error. I just deleted the old connection to see if it helps.
I will update you and let me know if i can provide other useful data to spot the issue.
Hi @Russ, thanks for your answer.
I haven't done any new connection after I set up the last one to make the automation works, now I can see that the new connection i made yesterday to fix the issue, is showing the same "Failed to verify connection 'My TRIGGERcmd connection'.  invalid_request"
I don't think i connected anything else, maybe I'm missing something but a do not believe so.
I set up an automation with integromat, it worked well, but it's the second time in 2 days that when i try to run this error happen, making a new connection(re-linking the integromat account to MyTriggerCMD) made it work again, but if not done manually the automation is broke.
