Maybe some of these tips will help.

  • Always provide as much detail as possible to your issue it may be important.

  • If applicable provide your SKETCH inside CODE TAGS ( </> ) or a CREATE share link.

  • If applicable provide a schematic even if hand drawn.

  • How to insert a picture into your post

  • If applicable provide a proper LINK to the hardware / sensors etc. you are using.
    COMMON ISSUES

  • Check you have a COMMON GROUND where required.

  • Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.

  • Try other computers where possible.

  • Try other USB leads where possible.

  • You may not have the correct driver installed. CH340/341 or CP2102

  • There may be a problem with the board check your wiring first.

  • Remove any items connected to pins 0 and 1.
    COMPUTER RELATED

  • close any other serial programs before opening the IDE.

  • Ensure you turn off any additional security / antivirus just to test.

  • There may be a problem with the PC try RESTARTING it.

  • You may be selecting the wrong COM port.

  • Avoid cloud/network based installations where possible OR ensure your Network/Cloud software is RUNNING.

  • Clear your browsers CACHE.

  • Close the IDE before using any other serial programs.

  • Preferably install IDE's as ADMINISTRATOR or your OS equivalent
    Arduino specific boards

  • NANO (Old Types) some require you to use the OLD BOOTLOADER option.

  • NANO (New Types) See the specific sections lower in the forum.

Performing the above actions may help resolve your problem without further help.

Yesterday I had a max7219 on my desk move to the monitor stand and then the port disappeared. I think it was shorting and thus the computer shut down the port. make sure you don't have anything like that.
