Forgot Password - Socket Exception Failure #2408

• ABP Framework version: v5.0.1
• UI type: Angular
• DB provider: EF Core
• Tiered (MVC) or Identity Server Separated (Angular): yes

Hello, I read some other tickets about email related topic. Firstly, I'm not sure *.Web layer is necessary for using sending email attributes.( should we add it ?) In here https://docs.abp.io/en/abp/latest/Emailing says " Setting Management module is already installed if you've created your solution from the ABP Startup template." We used abp startup template , so i dont define any settings in our appsettings.json(in *.IdentityServer). And as I understand from here, https://support.abp.io/QA/Questions/1338/How-to-send-email there is no need any code configuration . I can see email settings and templates in our UI page like below :

And I also read this https://docs.abp.io/en/abp/latest/Emailing#nullemailsender so , removed those debug mode lines.

When I tried forgot password , it gives this response :

Could you explain how can we handle this? Many thanks :)
