Error code 400 randomly occurs. Sometimes for long periods the acquisition on two channels works fine, sometimes no. The last case occurred on April 30, 2020 at 20:50:20 GMT+2 and continuing while I am writing (May 1st 07:40 GMT+2). All times this occurred I checked my Wi-Fi router and no problem was found. The acquisition interval for both channels is 120 s.
I suspect that for some reasons your server stops working and the problem is not in my software. Thank you.
P.S.
At 7:47:41 GMT+2, May 1st the acquisition started again without any action done.
