In Magento 2, this error is caused because the length of cache tags is more than 8192 characters. You can fix this error by increasing http_resp_hdr_len value in varnish configuration file.
I followed this tutorial https://magentoexplorer.com/magento-2-error-503-backend-fetch-failed-how-to-fix and successfully fixed that error.
Step 1:
Depend on your OS, navigate to:
Ubuntu: /etc/default/varnish
CentOS 6.x: /etc/sysconfig/varnish
CentOS 7.x: /etc/varnish/varnish.params
Step 2:
Edit config file and add the following line:
-p http_resp_hdr_len=42000
For example:
DAEMON_OPTS="-a ${VARNISH_LISTEN_ADDRESS}:${VARNISH_LISTEN_PORT}
-f ${VARNISH_VCL_CONF}
-T ${VARNISH_ADMIN_LISTEN_ADDRESS}:${VARNISH_ADMIN_LISTEN_PORT}
-t ${VARNISH_TTL}
-p thread_pool_min=${VARNISH_MIN_THREADS}
-p thread_pool_max=${VARNISH_MAX_THREADS}
-p http_resp_hdr_len=42000
Save file and restart your server. The error should be gone.
In mac + brew, I didsudo /usr/local/sbin/varnishd -n /usr/local/var/varnish -f /usr/local/etc/varnish/default.vcl -s malloc,1G -T 127.0.0.1:2000 -a 127.0.0.1:80 -F -p workspace_backend=128k -p http_resp_size=256k -p http_resp_hdr_len=42000
And that solves the issue. As it takes over the current terminal, I did this in new tab.

If your are struggling with cached 503 pages that the problem is there is no setting default cache tag for Varnish cache.
There are might be two options to struggle with empty cache tags.
Open your varnish configuration *.vcl file and in section sub vcl_backend_response
choose your option:
Add disabling cache:
if (!beresp.http.X-Magento-Tags) {
set beresp.ttl = 0s;
set beresp.uncacheable = true;
}
Add default tag
store
in case tags weren't passed:
if (!beresp.http.X-Magento-Tags) {
set beresp.http.X-Magento-Tags = "store";
}
In option "1" your "wrong" cases won't be cached.
In option "2" you will be able to drop cache for 503 or other "wrong" cases.

I was moving around attributes from groups to un-assigned group in Magento 2.10, I notice I was having issue with Varnish and the error was Varnish 503 Backend Fetch Failed.
The problem was in “clean_cache_by_tags” function in Magento. I think it’s an error clearing the cache in php7 & magento2.
solution define here

Thank you for your reply. In my case, this happened to a freshly installed MG and the issue turned to be that the server had Varnish disabled ( which I did myself earlier) while the Mag app had that setting enabled. I made sure that Varnish is disabled everywhere and the issue was solved. This was on Cloud hosting where Varnish can be disabled/enabled on both server and application level.

Save file and restart your server. The error should be gone.
In mac + brew, I didsudo /usr/local/sbin/varnishd -n /usr/local/var/varnish -f /usr/local/etc/varnish/default.vcl -s malloc,1G -T 127.0.0.1:2000 -a 127.0.0.1:80 -F -p workspace_backend=128k -p http_resp_size=256k -p http_resp_hdr_len=42000
And that solves the issue. As it takes over the current terminal, I did this in new tab.

In Magento 2, this error is caused because the length of cache tags is more than 8192 characters. You can fix this error by increasing http_resp_hdr_len value in varnish configuration file.
I followed this tutorial https://magentoexplorer.com/magento-2-error-503-backend-fetch-failed-how-to-fix and successfully fixed that error.
Step 1:
Depend on your OS, navigate to:
Ubuntu: /etc/default/varnish
CentOS 6.x: /etc/sysconfig/varnish
CentOS 7.x: /etc/varnish/varnish.params
Step 2:
Edit config file and add the following line:
-p http_resp_hdr_len=42000
For example:
DAEMON_OPTS="-a ${VARNISH_LISTEN_ADDRESS}:${VARNISH_LISTEN_PORT}
-f ${VARNISH_VCL_CONF}
-T ${VARNISH_ADMIN_LISTEN_ADDRESS}:${VARNISH_ADMIN_LISTEN_PORT}
-t ${VARNISH_TTL}
-p thread_pool_min=${VARNISH_MIN_THREADS}
-p thread_pool_max=${VARNISH_MAX_THREADS}
-p http_resp_hdr_len=42000
Save file and restart your server. The error should be gone.

If your are struggling with cached 503 pages that the problem is there is no setting default cache tag for Varnish cache.
There are might be two options to struggle with empty cache tags.
Open your varnish configuration *.vcl file and in section sub vcl_backend_response
choose your option:
Add disabling cache:
if (!beresp.http.X-Magento-Tags) {
set beresp.ttl = 0s;
set beresp.uncacheable = true;
}
Add default tag
store
in case tags weren't passed:
if (!beresp.http.X-Magento-Tags) {
set beresp.http.X-Magento-Tags = "store";
}
In option "1" your "wrong" cases won't be cached.
In option "2" you will be able to drop cache for 503 or other "wrong" cases.

I was moving around attributes from groups to un-assigned group in Magento 2.10, I notice I was having issue with Varnish and the error was Varnish 503 Backend Fetch Failed.
The problem was in “clean_cache_by_tags” function in Magento. I think it’s an error clearing the cache in php7 & magento2.

Thank you for your reply. In my case, this happened to a freshly installed MG and the issue turned to be that the server had Varnish disabled ( which I did myself earlier) while the Mag app had that setting enabled. I made sure that Varnish is disabled everywhere and the issue was solved. This was on Cloud hosting where Varnish can be disabled/enabled on both server and application level.
