Can't install extension from marketplace and with composer

Dears, i had created new magento storage (version 2.2.6). Right now i had installed theme and one extension with composer. I had connected My Web Extension manager to my magento market account, but it not shows any installations regarding my modules. Nevertheless i had installed one module with composer by guide (INSTALLATION LINK) . But now i had a problem installing module module link . Composer gives me error 

  [InvalidArgumentException]                                                                                                                                                      
  Could not find a matching version of package ulmod/ordercomment. Check the package spelling, your version constraint and that the package is available in a stability which ma  
  tches your minimum-stability (stable).

What can be a reason, does it means that i can't install this module to this version of magento ? File installation to coping it to app/code/ seams to be fine , but Store->Configuration stopped working complitely. Please help me to find solution. Thanks in advance.

I think the module is not compatible with the current version of your Magento website. Contact the developer of the module for further clarification.

Try downloading from the marketplace. It should work.

Might be the same issue I'm having: https://community.magento.com/t5/Installing-Extensions/Magento-Repo-packages-json-slow-to-update/m-p...

 

Maybe a system issue at Magento today?
