Critical resend ratio

Hello all,
I am new to 3D printing, I have a Creality ender 3 Pro with bl Touch installed.
motherboard 4.2.2 and Bios Merlin 1.1.2 from 2020.4.25.
I have Octoprint Version 1.5.2 installed from "octopi-buster-lite-0.17.0" on a 4 GB Raspberry pi 4.
The prints go perfectly well through the micro SD.
On the other hand as soon as I go through Octoprint I have this message displayed:

Critical resend ratio!
16% of transmitted lines have triggered resend requests. The communication with the printer is unreliable and this will cause print artefacts and failures.

Please see this FAQ entry on tips on how to solve this.

and it results in the printing of blockages, and large stain of material

What should I do to correct this problem?

Thanks in advance for any help!
Sincerely Pierre

Try a different USB cable. It is likely that there is some interference or general problems with the transmission over USB.

Try at least 2, if not 3. Aim for thicker cables. Read the FAQ article that the notification mentions?

I have tried several of different types and the message still appears.
I took the opportunity to try the OctoPi Release Candidate 0.18.0rc2 version, the message arrives later but the printer systematically fails

Make sure there are no other devices interfering, the cable is not folded, the printer's USB port is working properly.

I did read of a hack, to connect the ground pin of the Pi to the ground of the frame of the printer, something someone linked on a Creality forum.
