• Exception message and stack trace:
• We been deploy an Blazor server app, this app have only two modules, when the connected users goes to 50 or more, the statistics of CPU Usage reach to about 100%. The users reports that some components are crashed or take a long time to respond. In may case they have to reload the page but it doesn't works nither. Some users reports a websocket connetion error. We probe this app before in a poorer sever and we don't get this type of errors, the main diference is in the QA server we have ten o twelve connected users.
• Steps to reproduce the issue:"

Yes it was solved.. Thanks

Good Day @maliming No i haven't but I test with an app generate with abp suite and the error happens, i think it's about required validation. Memoedit is a control of Blazorise's suite, which it's the abp.io default generation for Blazor

• ABP Framework version: v4.4.2
• UI type: Blazor Server

• Tiered (MVC) or Identity Server Separated: yes
• Exception message and stack trace:
• Steps to reproduce the issue:
• Sometimes when the user is entering text, the characters that he has already written are overwritten with the new characters that he is entering, this motivated that the cursor is positioned several characters back and the previous text from that point simply disappears . It is not easy to reproduce, but you can see it happen more frequently when the person who is editing writes very fast.
• I record a video to show that.
• This error only happens with MemoEdit control, with other controls it doesn't happens.

Thanks @maliming

We changed the settings in SQL Server and afterwards the creation of tenants works fine.

• Steps to reproduce the issue: Generate a Blazor Server App

We been working on a Blazor (webAssembly) app, but we decide migrate to Blazor server, for get better performance on firsts loading.

Right now we been through some problems, one of then is User notify for validations and errors, in web assembly we got a modal windows message that indicate the error or validation. But now on Blazor server, we only get a console log notification in the browser.

Can anybody guide us for get older behaviour?

This is an example:

Before

The user left some field in blank

Now

Right now we got a message for reload page, and the user did not know what's happening

Thanks @maliming, problem was solved. It was reletated to activate TLS protocols on the server.

hi @maliming yes, i can share my screen. I send you an email.
