            <title>[BDS-17499] Unable to connect to BDS running on Ubuntu, while Windows version works</title>
                <link>https://bugs.mojang.com/browse/BDS-17499</link>
                <project id="11700" key="BDS">Bedrock Dedicated Server</project>
                    <description>&lt;p&gt;Just recently I updated my Minecraft servers to 1.19.2. The java servers ran just fine after update, but I noticed I was unable to join the bedrock one.&lt;/p&gt;

&lt;p&gt;So I tried going back to the previously working version of the bedrock server and tried connecting using my daugthers PC (which hadn&apos;t updated the minecraft client yet), but to no avail.&lt;/p&gt;

&lt;p&gt;The client shows &quot;connecting to multiplayer game&quot; for a couple of minutes and then it fails showing &quot;Connection timed out&quot; and &quot;Unable to connect to world&quot;. Same issue as with 1.19.2.&lt;/p&gt;


&lt;p&gt;I even went so far to reinstall the whole VM with a newer Ubuntu version.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;The server was initially a Ubuntu 20.04 VM and was updated to 22.04 (were I also had to download an earlier libssl to even get the bds server going).&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;The BDS server was running fine earlier this year. No issues connecting either PC client or Android clients over the internet or lan. The ports are forwarded correctly (since as I mentioned, it worked previosuly) and the ports are allowed access in UFW.&lt;/p&gt;

&lt;p&gt;VM Host is running Windows Server 2016.&lt;/p&gt;

&lt;p&gt;I tried installing the BDS server on a Windows 2016 VM instead and moved my world there (had to change the port forwards to that server ofc.) and that worked like a charm directly. Though that VM was not intended for hosting a game server.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Seems like this issue could be traced down to the Ubuntu version of BDS.&lt;/p&gt;</description>
                <environment>Ubuntu 22.04 VM (Hosted by Server 2016 Hyper-V), OpenJDK 17.0.4 (should not matter for the BDS server though), </environment>

&lt;p&gt;A traffic comparison between with and without the KB5015807 shows that the MC Client sends an ACK (0xc0), it passes through the Hyper-V HOST/Server, the Ubuntu server sees the ACK and responds with it&apos;s own ACK, but that ACK is not passed through the Hyper-V Host back the the client.&lt;/p&gt;</comment>

&lt;p&gt;I don&apos;t know if it helps, but if i run nmap on the Java servers, they appear as &quot;State Open&quot;, while the BDS shows as &quot;State Closed&quot;. Ports should however be opened in UFW and in my router.&lt;/p&gt;

&lt;p&gt;Can you copy or make a screenshot of server log and paste/attach it here?&lt;/p&gt;
