title: Rsync suddenly hanging when using recursive flag and on normal operations
body: <p>I'm using rsync to sync data from a VPS to a local storage NAS connected via a Wireguard tunnel.</p>
  <p>This has been working perfectly for months but I noticed a few weeks ago that syncs wouldn't complete anymore.</p>
  <p>I investigated a bit and found out that rsync just starts to hang in certain operations and eventually times out because of this. Here's the log from an rsync operation using -vvvrP flags:</p>
  <pre><code>opening connection using: ssh -l tali 192.168.6.2 rsync --server -vvvre.iLsfxC --partial . /home/tali/hdd/gitea/  (10 args)

  <p>It won't progress any further than this and hangs at this step forever.
  However I've found out that the operation completes successfully if I remove the -r flag. But obviously that means not all data is being transferred. (Same is true for -a which implies -r)</p>
  <p>I've also noticed a problem when transferring a singular file that already exists in the destination but has an older modification date. Rsync would also hang in this operation unless I added the -W flag. This made that singular operation work but had no effect on transferring directories with many files and sub-directories.</p>
  <p>I'd also like to add that this has worked flawlessly for months, I've recently moved so the destination, my local nas, is now on a different network. However I've already opened all relevant ports and verified the Wireguard tunnel works.</p>
  <p>Edit
  The local NAS is currently on a Fritz.Box router network. I'm suspecting that may be part of the issue since that is the only thing that changed, it was previously on another ISPs router in a different network</p>
  <p><strong>What I've tried</strong></p>
  <ul>
  <li><p>I've tried several different flag combinations also including -t and reducing verbosity all with the same problem.</p>
  </li>
  <li><p>I've verified that there's a connection to the destination NAS and that I can send testfiles through the tunnel using rsync.</p>
  </li>
  <li><p>I've verified that the destination has enough available space and that the partition and filesystem is clean and healthy</p>
  </li>
  </ul>
  <p>Finally here's a strace log of running the operation: <a href="https://pastebin.com/uZ3U75Es" rel="nofollow noreferrer">https://pastebin.com/uZ3U75Es</a></p>
  <p>Edit:</p>
  <p>I just verified that an rsync operation locally works flawlessly so the issue has to be somewhere in the network</p>
  <p>Edit 2:</p>
  <p>I ran Tshark on the destination device once with sending a single file which is known to work and once with the folder that makes rsync hang:</p>
  <p>Working single file:</p>
