This looks like a prusa. Is the feeder mounted on the head (call it "head mount") or does the feeder push the filament through a long bowden (call it "bowden")?
Well it looks like underextrusion briefly in one spot on each layer. and in a different spot. There are many possibilities, all of which can probably be fixed by the slicer.
For one, what is your retraction distance? For head mount it should be something around 1mm. for bowden it should be more like 4mm. Having a retraction distance too long will cause this issue I see on your print.
Also turn off acceleration control, jerk control, make sure "retraction on layer change" is off, make all the printing speeds (inner shell, outer shell, infill) all the same speed because when you speed up it can cause underextrusion like this briefly. You can turn all these features back on once you get things working/printing nicely.
Try to match up these defects with exactly what is happening in slice view. I would reload the gcode file into cura to be sure you have the EXACT same one and try to find one of these holes and try to see what is going on. Cura lets you "play" the part one move at a time. Dark blue lines are travel moves *with* retraction. Light blue lines are travel moves without retraction.

Thank you for your help!
I have direct extrusion and Retraction Distance settings in Cura was 6.5 mm by default.
Now I've changed it to 1 mm as you recommended and it works perfectly, no additional changes needed.
Thanks a lot!

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
