[Solved] Failed to connect to server(code:1006)

Generally, the VNC configuration of the/etc/Nova/nova.conf configuration file is improper

Open, replace with

2. Modify novncproxy_base_URL, try to use IP address instead of domain name

For server_proxyclient_Address if you use a domain name, you need to modify the resolution in the local host file

Add a line: IP addresses Domain name

After modification Systemctl restart openstack-nova-compute.service restart the service

Problem solving

Git push Failed to connect to localhost port 1080 [How to Solve]

Conclusion: it is caused by setting agent

1. Check the global settings

Enter git config -- Global - e to check whether there are proxy settings for [HTTP] and [HTTPS] in the global configuration, such as proxy= socks://localhost:1080, if any, delete it.

2. Check the config in the current. Git file

In the current working directory, cat ./.Git/config

As shown in the figure above, delete the agent.

Failed to connect to appears after burp suite agent is set

http://www.gstatic.com/generate_ two hundred and four

Burpsuite and browser settings are set normally, but an unknown port appears when capturing packets, and the domain name is unknown.

The reason is whether the upstream system agent is set in the user options of burpsuite, which is generally used for linkage scanning with awvs and Xray. If it is not closed here, it will be impossible to capture packets next time.

C++ Error: Invoking “make -j2 -l2“ failed [How to Solve]

Note that this prompt is not the problem, that is, the error is not invoking “make – J2 – L2”, it just indicates that you use dual threaded computing, just like the dual core of a computer. Similarly, “- J4 – L4” and “- J8 – L8” will appear. As shown in the figure above, the problem is that I missed a semicolon when writing C + + code;

Chunkloaderror caused by deleteoriginalassets: loading chunk * failed error

If you don’t say much, report the error directly:

this error report looks too familiar. After searching online, the general solution is:

1. Record an error in Vue history mode chunkloaderror: loading chunk XX failed net:: err_ Abort 404 (not found) solution

2. Error: loading chunk * failed, Vue router lazy loading error report solution

Follow the example. History, publicpath, onerror, and even the online server. Whatever solution you have, I can’t solve it. There’s no sign that it can be solved. I’m still a local project, and removing lazy loading can’t solve this problem. Why are such errors prompted?

In the end, experienced colleagues have to find the cause of the problem: delete original assets. Finally, just comment it out.

In vue.config.js, it is used to optimize the front-end performance: front-end performance optimization – using gzip compression.
