About connection issue.

Today we had a connection issue on 3 PC we was not able to estabilish connection with TeamViewer (we can no login in TV Program).

But we also was not able to open www.teamviewer.com

But on one computer all was fine.

We found solution that we had different TCP IP Settings on Ethernet card.

On 2 computers we had DHCP, on one computer IP adres there was staticly set.

on all this 3 computers DNS was set to our ROUTER.

Only on 4th computer which work properly all the time we had DNS set to local router and to google DNS 8.8.8.8

After using google DNS on this first 3 computers TeamViewer connectivity to main service as to www start works well.

Question:

As this used to work before, and stop works today, I want to ask: Do any DNS expert can explain what was the issue ?

    Hi @mLipok

    Great question and thanks for asking!

    Actually, the team is currently investigating exactly this to find out: what is the root cause (see our status page: https://status.teamviewer.com/)

    Please feel free to send in a ticket to our team with the following data to help them find it:

    • Public IP
    • Provider (ISP)
    • Support Collector

    Typing "ipconfig /flushdns" and press Enter in CMD / switching to google DNS 8.8.8.8 manually might help.

    Thanks and sorry for the issue today,

    Dear Community Manager,

    In this afternoon, my Teamviewer client can still connect to the Internet normally. But at night, the Teamviewer client prompts that there is no network and com cannot access https://www.teamviewer.com/. I ran Microsoft’s network diagnosis and prompted a DNS failure. After I manually set the DNS to 8.8.8.8, it was normal again.

    By the way, I am in Italy now, is there something wrong about DNS server in Italy?

    Best Regards
