yes, I removed timeout argument from the call. Here is a code now:<br>
```<br>
#!/usr/bin/env python<br>
from XRootD import client<br>
from XRootD.client.flags import OpenFlags<br>
f=client.File()<br>
redirector=&#39;root://cms-xrd-global.cern.ch&#39;<br>
#redirector=&#39;root://xrootd-cms.infn.it&#39;<br>
#redirector=&#39;root://cmsxrootd.fnal.gov&#39;<br>
fin=&#39;%s//store/data/Run2018C/Tau/NANOAOD/14Sep2018_ver3-v1/60000/6FA4CC7C-8982-DE4C-BEED-C90413312B35.root&#39; % redirector<br>
print(fin)<br>
data=f.open(fin, OpenFlags.READ)<br>
print(&quot;data&quot;, data)<br>
```<br>
and, I tried different redirectors.<br>
<br>
My suspicious it is related to the node iptables settings, the node is on a<br>
Internet2 and may be some settings should be applied to make requests pass<br>
through. But I don&#39;t know what xrootd requires (if any).<br>

&gt; Hi @vkuznet -<br>
&gt; <br>
&gt; For the last log snippet, can you confirm that you decreased the timeout value to be below the amount of time you waited?  It wasn&#39;t clear from your response whether this was so.<br>
