Error 0001b: trouble contacting crawling server

Hello, I have been using this plugin and have been very satisfied so far. However, the problem with Error 0001b has persisted for several days. Can you please advise me what to do? It’s been going on for a long time, and I’ve tried it at different times, so it won’t “fix itself”. ??

List of specific errors:

Error 0001b: trouble contacting crawling server. Please contact support. CMD: https://crawl.ljapps.com/crawlrevs?rip=46.28.106.188&surl=https%3A%2F%2Fzmijamakler.cz&stype=google&nhful=newest&locationtype=&scrapequery=ChIJ_0sl4nbjE0cR45nxbhb-Qrc&tempbusinessname=Makl%C3%A9%C5%99+Mgr.+Tom%C3%A1%C5%A1+Zmija

I need to resolve this relatively quickly or start using another plugin.
