Unable to connect to electrum after update to Version 0.4.0.1.

Electrum version 0.11.1:19

Bitcoin Knots 29.3:17

Later version of Sparrow as well.

All was working for over a year until the update.

Current errors:

If enabling SSL; Could not connect SOCKS: Connection refused. Check if the proxy server is running

Without SSL: Could not connect: Retries exhausted

Before the update in the URL in sparrow under server I did not specifically state 50001. It would just connect. Now with or without will NOT connect.  
I tried SSL, proxy 127.0.0.1 9150 no dice.

Also noticed the new OS has TOR 0.4.9.11:5 service running.

Any help would be appreciated.

wanted to give everyone an update JIC you ran into the same issue.

in sparrow do the following:

1- remove the electrum address

2- paste the same address back in the URL, set the port to 50001

3- close sparrow and restart

4- enable SSL, leave cert blank

5- close sparrow ad restart

6- do not enable proxy

7- Sparrow now connects.

in the end its a copy and paste of the same address into Sparrow with 50001 as port and enabling SSL

No T, No S etc..

hope that helps

Just a thought here. I had problem with another service. I had to import the StartOS cert into the machine I was running for it to work. My version of Sparrow was running on a machine that had the imported cert and connected to Electrum no problem. However, I changed over to using Falcrum because of the issues with previous versions of Electrum.
