Solved for me. I had this

Solved for me. 

I had this same problem.  I use a Linux tftp server with owner and group with same name as the username from the switch/ router I upload and download configs / images with.

Since the switch was not configured with username and I was not logged in with username, I was getting the timeout error. 

I changed the permissions on the file on the Linux box to allow others read access to the bin file in question and voilà I stopped receiving these errors.

I had the same problem. The fix for me was Windows Firewall. I allowed my TFTP Server app on both Private and Public and afterward the transfer worked first try.

Had timeout problem using Solarwinds TFTP on Windows 10.    The fix was to add Solarwinds TFTP Server to the allowed apps.  Only added it on the Private network. 

Had to browse to the folder the file was in to add it. 

"C:\Program Files (x86)\SolarWinds\TFTP Server\SolarWinds TFTP Server.exe".  

Works great now.

Hi,

Hi,

we had the same problem also after installing a new router, my colleague fixed by adding the following config line:

ip tftp source-interface interface_from_where_you_manage_router  (in our case it is a Loopback).

 

THIS WORKS FOR ME

Thank you for this.

Thank you for this. Specifying the correct source interface worked for me:

RT01(config)#ip tftp source-interface GigabitEthernet0/0.1
RT01(config)#end
RT01#copy startup-config tftp
Address or name of remote host []? 192.168.1.2 
Destination filename [rt01confg]?
!!
19118 bytes copied in 1.040 secs (18383 bytes/sec)

Re: Error opening tftp (Timed out)

I tried all those suggestions w/o any luck... I found out (the hard way lol) that from an isr, I had to increase the block size: ip tftp blocksize ,  default is ~512, make it 8k, https://www.cisco.com/c/en/us/support/docs/wireless/5760-wireless-lan-controller/117636-technote-tftpfile-00.html

 

Re: Error opening tftp (Timed out)

1. Go to Windows Firewall with Advanced Security on the TFTP/FTP Server

2. Add New Inbound Rule.

3. Specify IP/UDP/TCP Protocol and the specific port to allow (e.g If you are using SolarWinds TFTP Server Software, It works on UDP Port 69).

It worked for me. Hope it works for others if there is no other Firewall/ACL Rule implemented.

Re: Error opening tftp (Timed out)

I was having this issue with a new switch and this fixed it for me

 

conf t
no service config

 

Sometimes when switch first boots it may try to load a config from a tftp server and never stops thus the socket timeout

Re: Error opening tftp (Timed out)

We have the problem too with a Catalyst 9300 access switch and a Catalyst 9500 distribution, with vrf.

We testing with a catalyst 3850 and even these switch gives the error.

 

The solution we found, and works:

 

ip tftp blocksize 512

 

In an other situation we used 8192.

It works but we don't no why. Someone an explanation?

 

Best Regards, Harrie
