The red LED is lit and the blue LED flashes very quickly in succession. When I try to connect to the Nixie network via my mobile phone, the blue LED goes out for a while, the connection failed and the blue LED flashes quickly again.

Please have no idea where could there be a mistake?

Hello,
I disconnected the wifi module. The clocks went well until now, a moment ago to display time, date, etc. They lit up on each display number 4. So the clock shows the time, shows the date, passes the anode sequence and the number 4. It still helps everywhere.

The "44 44 44" always showing sounds like there is a short somewhere. Maybe a solder bridge or maybe there is touching or stuck to the back of the board - maybe a scrap of wire?

Look into it later when the dust is clearing off the crater.

The clock went for about a week without problems (except the WiFi module). They are placed on a wooden pad with columns and are covered with plexiglass to avoid them. Thus, there was no manipulation, nor a possible short circuit, etc. All 44 44 44 appeared out of nowhere.

Ok... so if I understand you, the 44 44 44 is always lit. True? What happens of you do a Factory Reset - is 44 44 44 still lit when the clock is "counting" during the first part of the reset?

One test you can try is to pull the 74141 (K155ID1) chip out of its socket. Power off, pull out chip, power on. What happens? Is 44 44 44 still there or are the tubes totally blank?
