<tt>The "DNS Problem Suspected" tag is set when the Atlas back-end doesn't see SOS messages. Probe/anchor sends SOS messages by means of DNS when it is about to connects to the registration server.</tt><br>

<pre>Hello,<o:p></o:p></pre>
<pre>Yesterday i got a notification that one of the our Anchors - #6262 has disconnected from Atlas. According to its Current Status info - DNS Problem Suspected. I see the anchor is configured to use the following DNS Resolvers - 8.8.8.8 and 2620:74:1b::1:1.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>The anchor responds to pings and is reachable from the world. Also the resolvers 8.8.8.8 are 2620:74:1b::1:1 reachable from the anchor's uplink router.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>So apart from checking the anchor's connectivity and DNS resolvers I don't have much left to do in order to get the anchor connected again.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Has anyone faced this situation before ?<o:p></o:p></pre>
