من یک برنامه وب فرم دارم که کلاینت signalr من می‌باشد. این برنامه در شرایط معمولی به درستی کار می‌کند و ارتباط برقرار می‌شود.

ولی زمانی که در کامپیوتر از kerio control vpn client  استفاده می‌کنم، و برنامه وب فرم را باز می‌کنم، برنامه در کنسول خطای زیر را نمایش می‌دهد:

متوجه شدم که خطا در این خط ایجاد می‌شود:

آیا می‌توانید در این مورد من رو راهنمایی کنید؟

JS Is Weird
JavaScript is a great programming language, but thanks to the fact that its initial release was built in only ten days back in 1995, coupled with the fact that JS is backward-compatible, it's also a bit weird. It doesn't always behave the way you might think. In this quiz, you'll be shown 25 quirky expressions and will have to guess the output. Even if you're a JS developer, most of this syntax is probably, and hopefully, not something you use in your daily life. 

With the release of Free Style 1.0, I figure it's about time to write about Free Style - how it works, why you'd want to use it and little introduction to CSS-in-JS. This has been a long time coming, with my first commit to Free Style over a year ago, and the first commit to Free Style in its current form 10 months ago. This is not a blog post designed to sway decisions - as always, you should use your own fair judgement. 

Echoing similar moves by MongoDB a couple of years ago, the creators of Elasticsearch are keen to ensure anyone offering Elasticsearch as a service contribute code back or license it commercially. This poses risks for Elasticsearch users, however, says VM Brasseur. 

Our final beta for Bootstrap 5 has come with some amazing new changes, including a new component!), documentation updates, and more. We’ve also fixed some important bugs since our last release, in particular with our dependencies. Next up is our stable release! 

Today, we are announcing .NET Core 3.0 Preview 8. Just like with Preview 7, we’ve focused on polishing .NET Core 3.0 for a final release and are not adding new features. If these final previews seem anti-climatic, that’s by design.

In Google we build all our software with a tool called Bazel. We’ve been using it for the past over 12 years to build projects with any size — from small internal apps, to large applications such as Gmail, Google Drive, and Google Cloud Console. 

In short, domain events help you to express, explicitly, the domain rules, based in the ubiquitous language provided by the domain experts. Domain events also enable a better separation of concerns among classes within the same domain. It's important to ensure that, just like a database transaction, either all the operations related to a domain event finish successfully or none of them do. Domain events are similar to messaging-style events, with one important difference. With real messaging, message queuing, message brokers, or a service bus using AMQP, a message is always sent asynchronously and communicated across processes and machines. This is useful for integrating multiple Bounded Contexts, microservices, or even different applications. However, with domain events, you want to raise an event from the domain operation you are currently running, but you want any side effects to occur within the same domain. The domain events and their side effects (the actions triggered afterwards that are managed by event handlers) should occur almost immediately, usually in-process, and within the same domain. Thus, domain events could be synchronous or asynchronous. Integration events, however, should always be asynchronous.
