In situations like these, there are several factors that could potentially prevent a client from accessing a website despite its functionality. Some possible explanations might include:

1. Local Network Issues: Occasionally, problems may arise within the client's local network, such as router configuration issues, firewall settings, or even temporary disruptions in internet connectivity. It would be helpful to ensure that the client's network setup is functioning correctly.

2. Browser Compatibility: Certain browser settings, extensions, or outdated versions can occasionally prevent website access. We recommend trying an alternate browser or clearing the cache and cookies of the current browser to see if it resolves the issue.

3. Firewall or Security Software: Antivirus programs or firewalls on the client's computer may sometimes block access to certain websites. Temporarily disabling these security measures or adding the website to the trusted sites list could be worth trying.

4. Geographical Restrictions: In some cases, websites may have specific geographical restrictions or access limitations due to licensing or legal reasons. However, if this were the case, we would have informed you beforehand.

Given that the website link has been confirmed to be functioning properly, we kindly request you check the aforementioned factors. If the issue persists, please provide us with any specific error messages or details you encounter, as they will assist us in further troubleshooting and resolving the problem.

Rest assured, we are committed to ensuring that you have uninterrupted access to our services, and we will continue to work diligently until this issue is resolved.
