Markaad booqato shabakad adeegsata HTTPS , waxay sidoo kale bixisaa  shahaadada SSL browserka si loo xaqiijiyo aqoonsigiisa. Iyadoo ay ku jiraan waxyaabo badan oo ku jira, hal shay oo ay ku jiraan waa URL -ka bogga. Haddii ay shahaadodu ku waafaqin waydo URL- ka waxa isticmaaluhu soo geliyey, waxay keeni doontaa digniin – Shahaadada Serverku kuma dhigma, ^{(Server’s certificate does not match,)} ERR CERT MAGACA GUUD EE AAN INVALID^{(ERR CERT COMMON NAME INVALID)} , iyo in xidhiidhku aanu ahayn mid gaar ah, oo goobta waxa laga yaabaa inay isku daydo inay xaddo kaaga. xogta. Maqaalkan, waxaan ku wadaagi doonaa sida loo hagaajiyo arrintan.

ERR_CERT_COMMON_NAME_INVALID

1] Hubi shahaadada

Haddii aad tahay mulkiilaha degelka ee helaya khaladkaas, waxaad u baahan tahay inaad hubiso in shahaadada si habboon loo rakibay, oo loogu habeeyey server-ka.

2] Hubi faylkaaga martida loo yahay

Windows waxay isticmaashaa faylka HOST^{(HOST file)} kaas oo marka hore la eego marka ay doonayso inay ku xalliso websaydka ciwaanka IP. Haddii fursad kasta, faylka martida loo yahay waxaa wax ka beddelay malware, waxay u wareejin doontaa degel xaasidnimo ah kaas oo u ekaan doona degelkii asalka ahaa laakiin cinwaan IP kale ah, oo aan lahayn shahaado SSL habboon . Hubi^(Make) in aad meesha ka saartid tusaale kasta oo ka mid ah mareegaha faylkaas oo kaydi

3] Isticmaal Google Public DNS

• Ugu horreyntii^(First) , midig-guji astaanta Shabakadda^(Network) shaqada oo dooro Network and Sharing Center .
• Dooro "Beddel Adapter Settings".
• Raadi xiriirka shabakada ee loo isticmaalo in lagu xiro internetka, doorashadu waxay noqon kartaa "Xiriirka Deegaanka" ama "Xiriirka Wireless".

Mid ka mid ah talooyinkan ayaa kaa caawin doona inaad saxdo qaladkan. Waxay ku dhici kartaa browser kasta sida Chrome , iwm, laakiin inta badan waa heerka PC ama dhibaatada heerka server.

Fix ERR_CERT_COMMON_NAME_INVALID error

When yoυ visit a website which uses HTTPS, it also offers an SSL certificate to the browser to verify its identity. While it does have a lot of things inside it, one thing it includes is thе URL of the website. In case the certificate does not match the URL to what user has entered, it will result in a warning – Server’s certificate does not match, ERR CERT COMMON NAME INVALID, and that the connection is not private, and the site may try to steal your data. In this post, we will share how to fix this issue.

ERR_CERT_COMMON_NAME_INVALID

1] Check the Certificate

If you are the website owner receiving that error, you need to check if the certificate is properly installed, and configured on the server.

2] Check your Host File

Windows uses a HOST file which is first checked when it wants to resolve the website to IP address. If by any chance, this host file has been modified by a malware, it will redirect to a malicious website which will look like the original website but on a different IP address, and without a proper SSL certificate. Make sure to remove any instance of the website in that file and save it.

3] Use Google Public DNS

• First of all, right-click on the taskbar Network icon and select Network and Sharing Center.
• Select “Change Adapter Settings”.
• Search for the network connection that is used to connect to the internet, the option might be either “Local Area Connection” or “Wireless Connection”.
• Right-click on it and click Properties.
• Choose the new window to select “Internet Protocol 4 (TCP/IPv4)” and then click the Properties button.
• Click the checkbox for “Use the following DNS server addresses” in the new window.
• Enter in 8.8.8.8 and 8.8.4.4
• Finally, click OK and exit.

One of these tips should help you to fix this error. It can happen in any browser like Chrome, etc, but is mostly a PC-level or a Server-level problem.
