 <h3>Blocked by telegram?</h3>
 <p>This may happen if to many or wrong requests are sent to api.telegram.org, e.g. using a invalid token or not existing API calls. If the block stay for longer time you can ask telegram service to unblock your IP-Adress.</p>
 <p>You can check with curl or wget if you are blocked by Telegram:</p>

 <p>Since Version 0.96 bashbot offers the option to recover from broken connections (aka blocked). Therefore you can provide a function named <code>bashbotBlockRecover()</code> in <code>mycommands.sh</code>. If the function exists it is called every time when a broken connection is detected.</p>
 <p>Possible actions are: Check if network is working, change IP-Adress or simply wait some time.</p>
 <p>If everything seems OK return 0 for retry or any non 0 value to give up.</p>
