Als c:geo niet kan inloggen op de geocaching-server, wordt er een waarschuwing weergegeven op het hoofdscherm:

Deze pagina biedt enkele controles die je moet doen om de reden voor het inlogprobleem te achterhalen. Volg de onderstaande stappen om de oorzaak van het probleem te vinden en je weer op weg te helpen.

Soms hebben wijzigingen op de geocaching-server ook een aanpassing aan c:geo-kant nodig. Verouderde c:geo-versies kunnen mogelijk niet langer inloggen of hebben andere problemen.

It is also possible, that the geocaching service itself has some outage and therefore c:geo cannot connect to it. Check if you can reach the website of your geocaching service using a web browser and that you can login on their website. For geocaching.com you can also check their status page to see, whether there are any known problems on their side.

Het is ook mogelijk dat de geocaching-service zelf een storing heeft en dat c:geo er daarom geen verbinding mee maken. Controleer of je de website van je geocachingdienst kunt bereiken via een webbrowser en of je op hun website kunt inloggen. Voor geocaching.com kun je ook op hun statuspagina kijken of er aan hun kant bekende problemen zijn.

Als je hebt geüpdatet naar de nieuwste c:geo-versie of al de nieuwste versie gebruikt en het probleem blijft bestaan, zorg er dan voor dat je een werkende netwerkverbinding hebt. C:geo kan niet inloggen zonder internetverbinding. Ook het gebruik van sommige antivirus- of firewall-apps kan het internetverkeer voor sommige apps blokkeren.

If you successfully checked your internet connection and the problem in c:geo still persists, you should check the authentication data you stored in c:geo.

To check your authentication please tap on the “Not logged in…” message box shown on the main screen.

Afterwards tap “Yes” to open the geocaching service configuration. Alternatively you can reach the service configuration from c:geo Menu → Settings → Services.

Select the geocaching service you want to check (e.g. geocaching.com), make sure it is activated and select “Update or remove authorization”.

This will open a screen, where you should again enter your username and password for that geocaching service. Afterwards select “Check authentication” to see if login is either now possible or what error is returned.

The following chapters provide an explanation and possible fixes for all error causes.

In 99% of cases, where this error message is shown, it really means, that you entered wrong credentials. Also, some special characters you may use in your username and/or password might look slightly different or can be confused with other characters on your Android keyboard.

This FAQ entry describes how to reset your password and/or lookup your username.

c:geo has detected, that the geocaching website requires you to solve a Captcha to login. c:geo therefore cannot login. geocaching.com might use such Captcha after detecting consecutive login failures (e.g. due to wrong password).

Furthermore geocaching.com might use such Captcha, when detecting logins from an suspicious, blacklisted or unidentified IP-address. Such might happen if you use VPN tools, anonymizers (like TOR) or some public Wi-Fi networks. Please deactivate such tools and try again to login with c:geo. You might also want to try logging in with c:geo using a different internet connection (e.g. mobile network instead of Wi-Fi).

You mail address and/or your account is not yet or no longer validated on the geocaching server.

In case you are using any anti-virus,firewall, Adblocker or VPN tool (e.g. F-Secure, AdAway, McAfee, Orbot, Corporate VPNs, TOR) please check if this might be blocking or disturbing your internet connection.

If the date/time is wrong this might lead to problems establishing a secure connection to the server.

Sometimes network providers insert messages into the HTML-traffic which prevents c:geo from logging in while on mobile network. A clear indication for this problem is, that c:geo only works on your Wi-Fi connection at home but not while on a mobile network.

Some final recommendations if none of the above solved your problem:

1. Make sure to also try the “long tap” to delete your authorization data in c:geo as described in step 4 on this page. This might help in rare case when outdated tokens,cookies or certificates are used due to data caching.
2. Consider de-installing and re-installing c:geo. After a new installation the installation wizard will help you to set up the connection as described in First steps with c:geo. You might want to perform a backup of your data in c:geo before doing this.
3. Contact our support team by using the menu “Report problem” on the c:geo main screen (behind the three dot button), provide a detailed problem description and also tell us you already followed all steps on this page.
