1  Bitcoin / Electrum / Re: Electrum Not Connecting to Any Server on: June 25, 2021, 07:24:21 AM
Is your Windows10 in the latest or at least newer build?
Most of the time, issues with inexplicable reason like this are likely caused by an unknown fault in the OS (since your W7 OS works).

Or try to re-install/update your network adapter's driver in the device manager:
  • Right-click Start icon, select "Device Manager" | or search for device manager.
  • Expand network adapters, and use "right-click>update driver" on your network adapter.
  • If it didn't do anything, reinstall it.

You might also want to remove any installed non-active network adapters that may cause connection issues, "view->show hidden devices".
Hidden devices have light-colored icons.

Or try ( like me) to use the portable (instead of Windows installer) version of Electrum placed into   one of WIN 10 folder (preferably on partition different from that one that holds OS). It carries all dependences and is less affective  to WIN 10 whims. Recommendation to add the access to  relevant folder via "Controlled folder access"  holds on.

Thanks for everyone's help, esp. NC50lc.  I downloaded the portable version, and everything works great right out of the box.  A couple of questions:
-  I'm using the same seed that I used for the installer version.  How does the portable program recognize the same seed?  Is it reaching out to the Electrum server to verify, or what?
- Are there any security compromises in using the portable version vs. installed version?
- Does the fact that the portable version works right out of the box narrow the scope of what's going on with my Win10 setup?  Cause there was one other program that I  had to abandon because my PC had issues with reaching out to its server for program updates.

Finally got access to the Ransome Ware Protection applet.  Added electrum-4.1.4.exe to Controlled Folder Access, but no luck.

Win10 has sophisticated threats protection  system. Try to add the access to  folder that holds Electrum: Go to settings, click Windows Security and then Virus&ThreadProtection. Find there Ransomeware protection section and click Manage ransomeware protection. Find "Controlled folder access" section in the opened window  and click "Allow an app trough Controlled folder access" (Choose YES in the pop-up window). Click "+Add an allowed app" button, then "Browse all apps"  and add   Electrum executive.

That's strange.  I don't see Ransomeware Protection in the location you suggested.  So I typed those words into the search box which does find it.  When I try to go there, I get the following response:

"Page not available.  Your IT Administrator has limited access to some areas of this app, and the item you tried to access is not available.  Contact IT helpdesk for more information."

Well, there is no IT administrator on my PC.  It's a home computer I built from scratch with Win10 Pro.  I'm the Administrator and only user. What is that about and how do I get around that?  I tried logging in as Administrator, but I still cannot enter Ransomeware Protection.

Yes, I've diabled Windows Firewall and Kaspersky anti-virus.  Still can't connect.  I have a Windows 7 base install on a different partition so I installed Electrum on it.  Works like a charm no issues.  So, there is some setting somewhere that is stopping Electrum from being able to connect to ouside servers, including Electrum itself (for updates).  I either have to re-install Win10, which I really don't want to do, or try another wallet and see if I get the same behavior.

This indicates that there's a problem with your internet connection, unless you haven't downloaded electrum from its official website.
That error should be displayed when you are not connected to internet. If you are connected to internet, it should say "Already up to date".  

Using a (secure) VPN or not using VPN (if you are using a VPN) may solve your problem.

Thanks.  I took your suggestion and activated the VPN that comes with Kaspersky, then opened Electrum.  When I go Help > Check for Updates it get the following feedback:

Update Check Failed
Sorry but we were unable to check for updates.
Please try again later.

HOWEVER, now it seems to actually be making an attempt to search for updates (it searches for about two seconds).  When VPN is off, I get the error message instantly, like it is not even making an attempt.  I guess that progess, of sorts.

I've researched all of your suggestions. 
- I did download Electrum 4.1.4 directly from Electrum home page.
- I re-installed Electrum, but no change in behavior.
- Went into Help > Check for Updates, and I get an error saying "Update Check Failed".
- There are no entries beneath "Connected Nodes"
- I am getting no warnings from Kaspersky or Windows Firewall when I start Electrum. 
- Went into Win10  Settings, clicked "Speech, region, date' , chose Date&Time and clicked Synch now.
- Reboot and re-started Electrum.

Without hiring a computer expert, looks like I won't be able to use Electrum.   What would be the next best alternative to Electrum, given that I am a newbie at Bitcoin?  Using Win10.

I just installed Electrum today, 6/19/21, on a Win10 machine.  When I open Electrum to the default wallet, it does not connect to any server.  The round icon in the lower right hand corner remains red.  What I've tried:
- Unchecking "Select Server Automatically" and tried assigning 10 different servers, but round icon remains red.
- Disabled windows firewall and my anti-virus, but no change in behavior.
- I went into windows firewall to allow the access to Electrum, but Electrum isn't even listed.

I seem to be out of options.  Any ideas?
