            <title>[MC-4148] cannot play lan games over ad-hoc mode</title>
                <link>https://bugs.mojang.com/browse/MC-4148</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;me and 2 friends are trying to do an IT project but we don&apos;t have internet at our school. so I went to network center on my pc and chose the option ad-hoc mode. our pc&apos;s connected and we all got 5 bars connection with 11 mbps.&lt;br/&gt;
when I opened my world to lan and he tried to connect he received an error: Internal exception: java.io.IOXxception:Received string length longer than maximum allowed (23 &amp;gt;16). on my world I got the message: .... joined the game and at the same moment I got the message ..... left the game. when I tried to join his lan world I just got the end of stream error the moment I pressed connect to server. we tried it the other way around and we got 1 time-out and one instant end of stream.&lt;/p&gt;

&lt;p&gt;we both got no crash report so if anyone tells me how I am supposed to get one please tell me.&lt;/p&gt;

&lt;p&gt;what I exptected to happen was: we had a fast connection so he would just join my world.&lt;br/&gt;
what actually happened: we weren&apos;t able to play on each other worlds.&lt;/p&gt;

&lt;p&gt;steps to reproduce:&lt;br/&gt;
1.place 2 pc&apos;s/laptops next to each other&lt;br/&gt;
2. go to neworkcentre and click on create new network.&lt;br/&gt;
3. choose the public option and choose a name for example: Mojang HQ&lt;br/&gt;
4. go to the other pc/laptop and connect with the Mojang HQ network.&lt;br/&gt;
5. wait a few seconds/ 1 minute untill you are connected. check the internet connection. it should be pretty good like at least 11mbps.&lt;br/&gt;
6. open your world to lan and let the other guy join your lan world.&lt;/p&gt;

&lt;p&gt;UPDATE: sometimes when your pc&apos;s are connected over ad-hoc the other pc doesn&apos;t even detect the lan world.&lt;/p&gt;</description>

In this ticket one of the &lt;b&gt;symptoms&lt;/b&gt; is described, but in &lt;a href=&quot;https://bugs.mojang.com/browse/MC-10363&quot; title=&quot;LAN worlds/servers still do not work when trying to login offline with an email, or are in a modified team.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-10363&quot;&gt;&lt;del&gt;MC-10363&lt;/del&gt;&lt;/a&gt; the &lt;b&gt;cause&lt;/b&gt;.&lt;br/&gt;
If you play ad-hoc you are naturally in offline mode, since no connection to an access point.&lt;/p&gt;

doesn&apos;t that mean that post &lt;a href=&quot;https://bugs.mojang.com/browse/MC-10363&quot; title=&quot;LAN worlds/servers still do not work when trying to login offline with an email, or are in a modified team.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-10363&quot;&gt;&lt;del&gt;MC-10363&lt;/del&gt;&lt;/a&gt; is the duplicate?&lt;/p&gt;</comment>

Please reopen, I really need this for my project&lt;/p&gt;</comment>
