TortoiseSVN unable to connect to VisualSVN
<p>Until last week we were normally able to connect to our VisualSVN server using Tortoise.</p>

<p>Yesterday it's not working anymore. Any attempt to connect results in error with message <code>Error running context: nenhuma conexão pôde ser feita porque a máquina de destino as recusou ativamente</code>. Yes, this portuga message means nothing and there are very few webpages talking about it.</p>

<p>Connection is made using HTTPS, I tried HTTP and SVN with no luck. I also tried to connect locally on the server, and strangely Tortoise hangs for some minutes and recovers reporting <code>Connection timed out</code>.</p>

<p>I tried restarting VisualSVN service. ALAIK firewall wasn't changed.</p>

<p>Strangely, if I use the same HTTPS URL on FireFox, it's answered and repository is shown as webpages!</p>

<p>Any idea on what may be causing this?</p>

<p>Update: I used <a href="https://support.microsoft.com/pt-br/kb/310099" rel="nofollow">PortQry</a> to connect to server using port 443, and it reported the port is listening. This means it's not a firewall issue and confirms FireFox being able to connect to VisualSVN. So, it's something related to TortoiseSVN.</p>

<p>Update 2: I tried command line <code>svn update</code> on my PC and got the same error message. Used the same command locally on the server, and it worked! This is getting strange.</p>

<p>Resuming: on my PC, both GUI and command line fail, but FireFox and PortQry work. Local on the server, command line works and GUI fails.</p>
