The message “does not allow connection” on Sharecloudy blocks access without providing any actionable explanation. The problem rarely originates from the service itself. It is most often due to a network filter, an outdated DNS cache, or a local security setting that rejects the request before it reaches the remote server.
DNS Filtering by French ISPs and Impact on Sharecloudy
For several years, several French internet service providers have implemented an automatic blocking of domains via filtered DNS. This policy targets sites deemed questionable, but it regularly affects perfectly legitimate cloud services. Sharecloudy can fall into this category if its domain appears on an overly broad filtering list.
The typical symptom: the site is inaccessible from the operator’s box or 4G, but works normally via another network or another DNS resolver. If you find that Sharecloudy loads correctly when tethering from a mobile on another operator, your ISP’s DNS filtering is the primary avenue to investigate.
To find out what to do if sharecloudy.com does not allow connection in this specific case, the most direct solution is to replace the DNS servers of your box or device with unfiltered public resolvers.
| DNS Resolver | Main IPv4 Address | Intrusive Filtering | Suitable for Unblocking |
|---|---|---|---|
| ISP DNS (default) | Variable by operator | Yes (active blacklists) | No |
| Cloudflare | 1.1.1.1 | No | Yes |
| Quad9 | 9.9.9.9 | Malware filtering only | Yes |
| Google Public DNS | 8.8.8.8 | No | Yes |
Changing DNS takes less than two minutes in the network settings of Windows, macOS, or directly in the administration interface of the box. This adjustment does not alter the connection speed or the overall security of the network.
Local Cache and Firewall: Invisible Blocks on Your Computer
When DNS is not the issue, the problem often lies with the machine itself. Two mechanisms frequently go unnoticed.
Expired Local DNS Cache
Your operating system retains recent DNS resolutions in memory. If the IP address of Sharecloudy has changed on the server side, your computer continues to query the old address, which no longer responds. Flushing the local DNS cache resolves this discrepancy immediately.
- On Windows, open the command prompt and type ipconfig /flushdns, then press enter
- On macOS, open the Terminal and run the command sudo dscacheutil -flushcache followed by sudo killall -HUP mDNSResponder
- On Linux, the command varies by distribution, but sudo systemd-resolve –flush-caches covers most recent cases
After flushing, restart the browser (not just the tab) before attempting access again.
Firewall and Antivirus Over-Filtering Outgoing Connections
Some antivirus programs, like Avast or Kaspersky, include a web filtering module that analyzes outgoing HTTPS connections. This module can block a cloud domain without visible notification, simply returning an error of the type “does not allow connection”.
The check is simple: temporarily disable the web shield of the antivirus, then reload Sharecloudy. If the page displays, the problem is identified. Then add the domain sharecloudy.com to the software’s exception list rather than leaving the shield disabled.
An active VPN can produce the same effect. The most documented example concerns NordVPN and its CyberSec function, which automatically blocks certain domains considered advertising or suspicious. Unchecking the “CyberSec: block ads and malicious websites” option in the VPN’s general settings is enough to lift the block.
Sharecloudy Connection Error Related to the Browser
The browser itself accumulates data that can interfere with authentication or loading a cloud service.
Expired or corrupted cookies associated with sharecloudy.com cause redirection loops that the browser interprets as a connection refusal. Deleting specific domain cookies and cache is more precise than a global cleanup: in Chrome, go to chrome://settings/siteData, search for “sharecloudy” and delete only those entries.
Browser extensions are another frequent trap. An ad blocker (uBlock Origin, AdBlock Plus) or a privacy protection module can intercept the service’s login scripts. Test by opening a private browsing window, which by default disables all extensions. If Sharecloudy works in private browsing, disable your extensions one by one to identify the one that is blocking.
Orphaned Administrator Accounts and Loss of Access to Cloud Service
This scenario mainly affects small and medium-sized enterprises. When an employee or contractor leaves the company without transferring the administrative rights of the Sharecloudy account, the administrator account becomes orphaned and no one can manage access anymore.
The symptom differs from network blocking: the username and password seem correct, but the service refuses the connection or displays a suspended account status. The password recovery procedure also does not work if the email address associated with the admin account has been deactivated with the departure of the collaborator.
Prevention involves a clear mapping of the SaaS and cloud accounts used in the organization, with systematic identification of who holds the rights to each service. In case of blocking, the only recourse is to contact Sharecloudy’s support, providing proof of account ownership (invoice, verified domain, identity of the legal representative).
Access blocking to Sharecloudy is resolved in the vast majority of cases by changing DNS or cleaning the local cache. If these two actions are insufficient, the firewall, VPN, or a browser extension are almost always responsible. The orphaned account case remains the only one that requires human intervention on the publisher’s side.
