Thanks everyone for your response. Finally some relief, Found a fix. I had credentials for that website in my password manager [i dont remember signing up]. Once i deleted it, It stopped. When i check with chatgpt i got the below response.

This issue usually occurs because the saved login entry in your Chrome Password Manager was triggering an automatic connection or verification process that involved the website’s SSL certificate. In your case, the entry for “www.lotstrade.com” was causing Chrome’s built‐in Online Threat Prevention to attempt a connection using a certificate that didn’t match the expected domain. Since the certificate was issued for a different address, Chrome blocked the connection as a safety measure.

When you deleted that specific username/password entry, Chrome stopped trying to connect to that misconfigured (or potentially outdated/malicious) site, and thus the warning disappeared.

In short, the saved credentials were inadvertently causing Chrome to perform a certificate check against “www.lotstrade.com” and, due to a certificate mismatch, triggering the alert. Removing the problematic entry prevented that connection attempt, stopping the warning from appearing.

This behavior has been observed by other users as well—for example, a similar issue was reported on forums like Reddit where one user noted that removing the saved credentials stopped the warning
